Name: Bis(acetylacetone)copper And the article was included in Nano Letters in 2020. The article conveys some information:

Atomic edge sites on two-dimensional (2D) nanomaterials display striking catalytic behavior, whereas edge engineering for 2-dimensional metal nanocatalysts remains an insurmountable challenge. Here the authors advance a 1-pot synthesis of ultrathin 2-dimensional PdPtCu trimetallic nanosheets and nanorings with escalating low-coordinated edge proportions from 11.74% and 23.11% to 45.85% as cutting-edge EtOH oxidation reaction (EOR) electrocatalysts. This in situ edge enrichment hinges on a competitive surface capping and etching strategy with integrated manipulation of the reaction kinetics. Electrocatalysis tests demystify an edge-relied EOR performance, where the edge-richest 9.0 nm-Pd61Pt22Cu17 nanorings attain an exceptional activity (12.42 A mg-1Pt+Pd, 20.2 times that of com. Pt/C) with substantially improved durability. Molecularly mechanistic studies certify that the unsaturated edge sites on these 2-dimensional catalysts prevail, triggering the C-C bond scission and succeeding CO removal to facilitate a 12-electron-transferring EOR process. This study introduces the metal-edge-driven concept and enables the edge sites on 2-dimensional multimetallic nanocatalysts technique to design versatile heterocatalysts.

《Boosting Potassium Storage Performance of the Cu2S Anode via Morphology Engineering and Electrolyte Chemistry》 was written by Peng, Qingkui; Zhang, Shipeng; Yang, Hai; Sheng, Binbin; Xu, Rui; Wang, Qingsong; Yu, Yan. COA of Formula: C10H16CuO4 And the article was included in ACS Nano in 2020. The article conveys some information:

Transition metal sulfides (TMSs) have been demonstrated as attractive anodes for potassium-ion batteries (KIBs) due to the high capacity, abundant resource, and excellent redox reversibility. Unfortunately, practical implementation of TMSs to KIBs is still hindered by the unsatisfactory cyclability and rate performance which result from the vast volume variation during charge/discharge processes. Herein, a uniform nitrogen-doped carbon coated Cu2S hollow nanocube (Cu2S@NC) is designed as an anode material for the KIB, which displays an outstanding cycle performance (317 mAh g-1 after 1200 cycles at 1 A g-1) and excellent rate capacity (257 mAh g-1 at 6 A g-1) in a half-cell. The hollow nanosized structure can both shorten the diffusion length of potassium ions/electrons and buffer the volume expansion upon cycling. Besides, the high concentration electrolyte is beneficial to form the stable solid electrolyte interphase (SEI) film, reducing the interface impedance and enhancing the cycling stability. Ex situ transmission electron microscopy (TEM) and ex situ X-ray diffraction (XRD) reveal the reaction mechanism of Cu2S@NC. In addition to this study using Bis(acetylacetone)copper, there are many other studies that have used Bis(acetylacetone)copper(cas: 13395-16-9COA of Formula: C10H16CuO4) was used in this study.

The article was titled 《From one-dimensional to two-dimensional wurtzite CuGaS2 nanocrystals: non-injection synthesis and photocatalytic evolution》. The information in the text is summarized as follows:

Multinary copper-based chalcogenides exhibit significant performance in photocatalytic hydrogen evolution due to their suitable optical bandgap for visible light absorption and environmentally friendly character. Herein, high-quality wurtzite CuGaS2 (CGS) nanocrystals (NCs) were synthesized by using a one-step heating-up process without any injection, and the morphol. could be tuned from one-dimensional (1D) to two-dimensional (2D) by precise choice of surface ligands and gallium precursors. The formation mechanism of CGS NCs was studied comprehensively by means of the temporal-evolution of the morphol., crystal structure and optical absorption results. The reaction started from djurleite Cu31S16 NCs, and then proceeded with the formation of Cu31S16-CGS heteronanostructures (HNS), and finally the transformation from HNS to monophasic CGS nanorods took place with prolonging of the synthesis time. The optical bandgap and the energy level of the different-dimensional CGS NCs exhibited a strong dependence on the morphol. change, which correlated with the percentage of the exposed {001} and {100} facets. The theor. calculation based on d. functional theory (DFT) revealed that the (001) surface facilitated the charge transport rather than the (100) surface, which was consistent with the electrochem. impedance spectroscopy (EIS) results. As a result, the 2D CGS nanoplates with more exposed {001} facets exhibited an attractive photocatalytic hydrogen production activity under simulated solar illumination as compared to 1D and quasi-2D counterparts. This study demonstrates that control over the dimension of I-III-V group semiconductor NCs could lead to a significant improvement of the photocatalytic hydrogen evolution.Bis(acetylacetone)copper(cas: 13395-16-9Computed Properties of C10H16CuO4) was used in this study.

《Ultrasmall Alloy Nanozyme for Ultrasound- and Near-Infrared Light-Promoted Tumor Ablation》 was written by Jana, Deblin; Wang, Dongdong; Bindra, Anivind Kaur; Guo, Yi; Liu, Jiawei; Zhao, Yanli. Category: copper-catalystThis research focused onultrasmall alloy nanozyme ultrasound IR tumor ablation; alloy; chemodynamic therapy; nanozyme; photothermal therapy; ultrasound. The article conveys some information:

The therapeutic effect of chemodynamic therapy (CDT) is significantly restricted by the stern reaction conditions and slow reaction rate of the Fenton reaction (pH 3-4). Herein, we report an ultrasmall trimetallic (Pd, Cu, and Fe) alloy nanozyme (PCF-a NEs) possessing dynamic active-site synergism, thus exhibiting a cascade glutathione peroxidase and peroxidase (POD) mimicking activities in circumneutral pH. PCF-a NEs exhibit photothermally augmented POD property and high photothermal conversion efficiency (62%) for synergistic tumor cell apoptosis. In addition, ultrasound can also enhance the mass transfer at active catalytic sites of PCF-a NEs, in turn accelerating Fenton-like reaction for tumor-specific CDT. This work provides a strategy for engineering alloy nanozymes in a bioinspired way for the amplification of intratumor reactive oxygen species in response to external stimuli, demonstrating enhanced efficiency for the inhibition of tumor growth in vitro and in vivo. The results came from multiple reactions, including the reaction of Bis(acetylacetone)copper(cas: 13395-16-9Category: copper-catalyst)

The article was titled 《Insights into Nucleation and Growth of Colloidal Quaternary Nanocrystals by Multimodal X-ray Analysis》.Safety of Bis(acetylacetone)copper The article contains the following contents:

Insights in the nucleation and growth during synthesis of anisotropic Cu2ZnSnS4 nanocrystals were revealed by simultaneously performing in situ x-ray absorption spectroscopy (XAS) and small-angle x-ray scattering (SAXS). Real-time XAFS reveals that upon thiol injection into the reaction flask, a key Cu thiolate intermediate species is formed within fractions of seconds, which decomposes further within a narrow temperature and time window to form Cu sulfide nanocrystals. These nanocrystals convert into Cu2ZnSnS4 nanorods by sequentially incorporating Sn and Zn. Real-time SAXS and ex situ TEM of aliquots corroborate these findings. Combined in situ x-ray absorption and small-angle x-ray scattering enables the understanding of mechanistic pathways in colloidal nanocrystal formation.

The article was titled 《Dual Targeting with Cell Surface Electrical Charge and Folic Acid via Superparamagnetic Fe3O4@Cu2-xS for Photothermal Cancer Cell Killing》.Product Details of 13395-16-9 The article contains the following contents:

A major challenge in cancer therapy is to achieve high cell targeting specificity for the highest therapeutic efficacy. Two major approaches have been shown to be quite effective, namely, (1) bio-marker mediated cell targeting, and (2) elec. charge driven cell binding. The former utilizes the tumor-specific moieties on nano carrier surfaces for active targeting, while the latter relies on nanoparticles binding onto the cancer cell surfaces due to differences in elec. charge. Cancer cells are known for their hallmark metabolic pattern: high rates of glycolysis that lead to neg. charged cell surfaces. In this study, the nanoparticles of Fe3O4@Cu2-xS were rendered pos. charged by conjugating their surfaces with different functional groups for strong electrostatic binding onto the neg.-charged cancer cells. In addition to the pos. charged surfaces, the Fe3O4@Cu2-xS nanoparticles were also modified with folic acid (FA) for biomarker-based cell targeting. The dual-targeting approach synergistically utilizes the effectiveness of both charge- and biomarker-based cell binding for enhanced cell targeting. Further, these superparamagnetic Fe3O4@Cu2-xS nanoparticles exhibit much stronger IR absorptions compared to Fe3O4, therefore much more effective in photothermal therapy.

《Seed-mediated growth of heterostructured Cu1.94S-MS (M = Zn, Cd, Mn) and alloyed CuNS2 (N = In, Ga) nanocrystals for use in structure- and composition-dependent photocatalytic hydrogen evolution》 was published in Nanoscale in 2020.

Product Details of 13395-16-9 The article mentions the following:

Multinary copper-based chalcogenide nanocrystals (NCs) as light-driven photocatalysts have attracted extensive research interest due to their great potential for generating sustainable energy without causing environmental concerns. However, systematic studies on the growth mechanism and related photocatalytic activities involving different valent metal ions (either M2+ or N3+) as foreign cations and monoclinic Cu1.94S NCs as the ‘parent lattice’ have rarely been carried out. In this work, we report an effective seed-mediated method for the synthesis of heterostructured Cu1.94S-MS NCs (M = Zn, Cd and Mn) and alloyed CuNS2 NCs (N = In and Ga). A typical cation exchange process took place prior to the growth of heterostructured NCs, while further inter-cation diffusion occurred only for the alloyed NCs. When compared with Cu1.94S NCs, all the heterostructured Cu1.94S-MS NCs and CuGaS2 NCs showed enhanced photocatalytic activities toward hydrogen production by water splitting, owing to their tailored optical band gaps and energy level alignments. Although optically favored, CuInS2 ANCs were not comparable to others due to their low conduction band min. for the reduction of H2O to H2.

Multicomponent quantum nanostructures have attracted significant attention due to their potential applications in photovoltaics, optoelectronics and bioimaging. However, the preparation of anisotropic quaternary nanoheterostructures such as Cu-In-Zn-S(Se) (CIZS and CIZSe) is still very poorly explored and understood. Here, we report the synthesis and studies of NIR emissive CIZSe/CIZS/ZnS core/shell/shell nanoheterostructures with a unique hetero-nanonail (HNN) morphol. In our approach, wurtzite (WZ) CIZSe/CIZS core/shell QDs have been prepared by depositing a CIZS shell onto a previously synthesized chalcopyrite CIZSe QD core using a seeded growth technique. Following careful control of the ZnS shell growth resulted in the formation of the distinct nail-like CIZSe/CIZS/ZnS nanoheterostructure, where the CIZSe/CIZS core/shell QD is located near the ”head” of the nail. The emission in the NIR region of the CIZSe/CIZS/ZnS nanocrystals is assigned to the CIZSe/CIZS core/shell quantum nanostructure. The CIZSe/CIZS/ZnS HNNs are particularly interesting due to a range of potential applications including bioimaging, biosensing, energy harvesting and NIR photodetectors. Finally, we also report the successful controlled growth of gold nanoparticles on the surface of the CIZSe/CIZS/ZnS nanonail-like heterostructure and the investigation of the resulting multimodal nanocomposites.

In 2022,Wang, Jingwei; Yan, Hongliang; Li, Xinxue published an article in Energy & Fuels. The title of the article was 《Synthesis of PtCu Rhombic Dodecahedral Nanoframes Decorated with Six Nanobranches for Efficient Methanol Electrooxidation》.Category: copper-catalyst The author mentioned the following in the article:

Engineering the structure of metal nanocrystals is critical to optimize their catalytic performance. In recent years, nanoframes have emerged as potential catalysts owing to their high at. utilization, abundant catalytically active sites, and three-dimensional accessible surfaces. Herein, PtCu rhombic dodecahedral nanoframes (RDFs) were synthesized via a facile one-pot solvothermal method by using hexadecyltrimethylammonium bromide as the structure-directing and stabilizing agent. Notably, the prepared PtCu RDFs each contain six nanobranches selectively protruding from their six 〈100〉 vertices. The nanobranches possess various high-index facets, which may act as highly active sites for electrochem. catalysis. Electrocatalytic measurements demonstrate that the prepared PtCu RDFs have superior catalytic activity and stability relative to the Pt/C catalyst for the methanol oxidation reaction (MOR). We hope that this synthetic approach will introduce new insights into the construction of Pt-based nanostructures for the MOR or other catalytic applications. The experimental part of the paper was very detailed, including the reaction process of Bis(acetylacetone)copper(cas: 13395-16-9Category: copper-catalyst)

Chen, Alexander N.; Endres, Emma J.; Ashberry, Hannah M.; Bueno, Sandra L. A.; Chen, Yifan; Skrabalak, Sara E. published an article in 2021. The article was titled 《Galvanic replacement of intermetallic nanocrystals as a route toward complex heterostructures》, and you may find the article in Nanoscale.Synthetic Route of C10H16CuO4 The information in the text is summarized as follows:

Galvanic replacement reactions are a reliable method for transforming monometallic nanotemplates into bimetallic products with complex nanoscale architectures. When replacing bimetallic nanotemplates, even more complex multimetallic products can be made, with final nanocrystal shapes and architectures depending on multiple processes, including Ostwald ripening and the Kirkendall effect. Galvanic replacement, therefore, is a promising tool in increasing the architectural complexity of multimetallic templates, especially if we can identify and control the relevant processes in a given system and apply them more broadly. Here, we study the transformation of intermetallic PdCu nanoparticles in the presence of HAuCl4 and H2PtCl6, both of which are capable of oxidizing both Pd and Cu. Replacement products consistently lost Cu more quickly than Pd, preserved the crystal structure of the original intermetallic template, and grew a new phase on the sacrificial template. In this way, at. and nanometer-scale architectures are integrated within individual nanocrystals. Product morphologies included faceting of the original spherical particles as well as formation of core@shell and Janus-style particles. These variations are rationalized in terms of differing diffusion behaviors. Overall, galvanic replacement of multimetallic templates is shown to be a route toward increasingly exotic particle architectures with control exerted on both Angstrom and nanometer-scale features, while inviting further consideration of template and oxidant choices.Bis(acetylacetone)copper(cas: 13395-16-9Synthetic Route of C10H16CuO4) was used in this study.
