The article was titled 《High-Index Faceted PdPtCu Ultrathin Nanorings Enable Highly Active and Stable Oxygen Reduction Electrocatalysis》, and you may find the article in Small Methods.Quality Control of Bis(acetylacetone)copper The information in the text is summarized as follows:

Ultrathin nanosheet catalysts deliver great potential in catalyzing the oxygen reduction reaction (ORR), but encounter the ceiling of the surface at. utilizations, thus presenting a challenge associated with further boosting catalytic activity. Herein, a kind of PdPtCu ultrathin nanorings with increased numbers of electrocatalytically active sites is reported, with the purpose of breaking the activity ceiling of conventional catalysts. The as-made PdPtCu nanorings possess abundant high-index facets at the edge of both the exterior and interior surfaces. An ultrahigh electrochem. active surface area of 92.2 m2 g-1PGM is achieved on this novel catalyst, much higher than that of the com. Pt/C catalyst. The optimized Pd39Pt33Cu28/C shows a great enhanced ORR activity with a specific activity of 2.39 mA cm-2 and a mass activity of 1.97 A mg-1PGM at 0.9 V (vs. RHE), as well as superior durability within 30 000 cycles. D. function theory calculations reveal that the high-index facets and alloying Cu atoms can optimize the oxygen adsorption energy, explaining the enhanced ORR activity. Overcoming a key tech. barrier in sub-nanometer electrocatalysts, this work successfully introduces the hollow structures into the ultrathin nanosheets, heralding the exciting prospects of high-performance ORR catalysts in fuel cells.

Synthetic Route of C10H16CuO4 And the article was included in ACS Catalysis in 2020. The article conveys some information:

Tuning the compositions and structures of Pd-based nanomaterials and their supports has shown great potentials in facilitating the sluggish ethanol oxidation reaction (EOR) in alk. direct ethanol fuel cells. Accordingly, a facile solvothermal method involving Cu and Pd composition migrations is developed in this study, to synthesize highly uniform and small-sized nanospheres (NSs) possessing the special structures of composition-graded (CG) Cu1Pd1 and surface-doped (SD) Ir0.03, which are evenly anchored onto N-doped porous graphene (NPG) as a high-performance EOR electrocatalyst (CGCu1Pd1/SDIr0.03 NSs/NPG). Comprehensive physicochem. characterizations, electrochem. analyses, and first-principles calculations reveal that, benefiting from the NPG-imparted mass-transfer and oxygen-reduction effects, the CG-SD structural and size-morphol. effects of the NS, as well as the Cu- and Ir-induced bifunctional, geometric, and ligand effects, CGCu1Pd1/SDIr0.03 NSs/NPG exhibits not only ultrahigh electrocatalytic activity and highly efficient noble-metal (NM) utilization, showing 7105 and 6685 mA mg-1 in Pd- and NM-mass-specific activity (MSA), resp., which are 15.8 and 14.9 times those of com. Pd/C, but also satisfactory electrocatalytic durability, retaining resp. 28.1- and 19.2-fold enhancements in Pd-MSA compared to the com. Pd/C, after 1 h chronoamperometric and 500-cycle potential cycling degradation tests. This study not only provides an effective and versatile synthetic strategy to prepare the NM-efficient metal-based nanomaterials with the special CG and SD structures for various electrocatalytic and energy-conversion applications, but also proposes some insights into the composition- and structure-function relations in EOR electrocatalytic mechanism for rationally designing highly active and durable EOR electrocatalysts.

Synthetic Route of C10H16CuO4 The article mentions the following:

The at.-level understanding of the dynamic evolution of the surface structure of bimetallic nanoparticles under industrially relevant operando conditions provides a key guide for improving their catalytic performance. Here, the authors exploit operando x-ray absorption fine structure spectroscopy to determine the dynamic surface reconstruction of Cu/Au bimetallic alloy where single-atom Cu was embedded on the Au nanoparticle, under electrocatalytic conditions. The authors identify the migration of isolated Cu atoms from the vertex position of the Au nanoparticle to the stable (100) plane of the Au 1st atom layer, when the reduction potential is applied. D. functional theory calculations reveal that the surface atom migration would significantly modulate the Au electronic structure, thus serving as the real active site for the catalytic performance. These findings demonstrate the real structural change under electrochem. conditions and provide guidance for the rational design of high-activity bimetallic nanocatalysts. In the part of experimental materials, we found many familiar compounds, such as Bis(acetylacetone)copper(cas: 13395-16-9Synthetic Route of C10H16CuO4)

We report the synthesis of air-stable Cu nanoparticles (NPs) using the bottom-up laser reduction in liquid method. Precursor solutions of copper acetlyacetonate in a mixture of methanol and iso-Pr alc. were irradiated with femtosecond laser pulses to produce Cu NPs. The Cu NPs were left at ambient conditions and analyzed at different ages up to seven days. TEM anal. indicates a broad size distribution of spherical NPs surrounded by a carbon matrix, with the majority of the NPs less than 10 nm and small numbers of large particles up to ~100 nm in diameter XRD collected over seven days confirmed the presence of fcc-Cu NPs, with some amorphous Cu2O, indicating the stability of the zero-valent Cu phase. Raman, FTIR, and XPS data for oxygen and carbon regions put together indicated the presence of a graphite oxide-like carbon matrix with oxygen functional groups that developed within the first 24 h after synthesis. The Cu NPs were highly active towards the model catalytic reaction of para-nitrophenol reduction in the presence of NaBH4.

《Yttrium doped copper (II) oxide hole transport material as efficient thin film transistor》 was written by Baig, Sadia; Kumar, Pankaj; Ngai, Jenner; Li, Yuning; Ahmed, Safeer. Recommanded Product: Bis(acetylacetone)copperThis research focused ontransistor thin film yttrium doped copper oxide hole transport; copper oxide; doping; thin films; transistor; yttrium.. The article conveys some information:

This work reports development of yttrium doped copper oxide (Y-CuO) as a new hole transport material with supplemented optoelectronic character. The pure and Y-doped CuO thin films are developed through a solid-state method at 200°C and recognized as high performance p-channel inorganic thin film transistors (TFTs). CuO is formed by oxidative decomposition of copper acetylacetonate, yielding 100 nm thick and conductive (40.9 S cm-1) compact films with a band gap of 2.47 eV and charge carrier d. of ∼1.44×1019 cm-3. Yttrium doping generates denser films, Cu2Y2O5 phase in the lattice, with a wide band gap of 2.63 eV. The elec. conductivity increases 9-fold on 2% Y addition to CuO, and the carrier d. increases to 2.97×1021 cm-3, the highest reported so far. The TFT devices perform remarkably with high field-effect mobility (μsat) of 3.45 cm2 V-1 s-1 and 5.3 cm2 V-1 s-1, and considerably high current-on/off ratios of 0.11×104 and 9.21×104, for CuO and Y-CuO films, resp. (at -1 V operating voltage). A very small width hysteresis, 0.01 V for CuO and 1.92 V for 1% Y-CuO, depict good bias stability. Both the devices work in enhancement mode with stable output characteristics for multiple forward sweeps (5 to -60 V) at -1Vg.

These research results belong to Chen, Dong; Wang, Yanlei; Liu, Danye; Liu, Hui; Qian, Cheng; He, Hongyan; Yang, Jun. SDS of cas: 13395-16-9 The article mentions the following:

Tuning the surface composition of noble metal nanoparticles by alloying with other metals represents a powerful strategy to boost their electrocatalytic selectivity. In this report, ultrafine CuPd nanoalloys with the particle size of ca. 2 nm are synthesized based on the galvanic replacement reaction between presynthesized Cu nanoparticles and Pd2+ precursors, and the tuning of their surface compositions is also achieved by changing the atom ratios of Cu/Pd. For the electrocatalytic reduction of CO2, Cu5Pd5 nanoalloys show the CO Faradaic efficiency (FE) of 88% at -0.87 V, and the corresponding mass activity reaches 56 A/g that is much higher than those of Cu8Pd2 nanoalloys, Cu3Pd7 nanoalloys and most of previously reported catalysts. D. functional theory uncovers that with the increase of Pd on the surface of the ultrafine CuPd nanoalloys, the adsorbed energy of both of intermediate COOH* and CO* to the Pd sites is strengthened. The Cu5Pd5 nanoalloys with the optimal surface composition better balance the adsorption of COOH* and desorption of CO*, achieving the highest selectivity and activity. The difficult liberation of absorbed CO* on the surface of Cu3Pd7 nanoalloys provides carbon source to favor the production of ethylene, endowing the Cu3Pd7 nanoalloys with the highest selectivity for ethylene among these ultrafine CuPd nanoalloys.

The article was titled 《Grain-boundary segregation of magnesium in doped cuprous oxide and impact on electrical transport properties》, and you may find the article in Scientific Reports.Name: Bis(acetylacetone)copper The information in the text is summarized as follows:

In this study, we report the segregation of magnesium in the grain boundaries of magnesium-doped cuprous oxide (Cu2O:Mg) thin films as revealed by atom probe tomog. and the consequences of the dopant presence on the temperature-dependent Hall effect properties. The incorporation of magnesium as a divalent cation was achieved by aerosol-assisted metal organic chem. vapor deposition, followed by thermal treatments under oxidizing conditions. We observe that, in comparison with intrinsic cuprous oxide, the electronic transport is improved in Cu2O:Mg with a reduction of resistivity to 13.3 ± 0.1 Ω cm, despite the reduction of hole mobility in the doped films, due to higher grain-boundary scattering. The Hall carrier concentration dependence with temperature showed the presence of an acceptor level associated with an ionization energy of 125 ± 9 meV, similar to the energy value of a large size impurity-vacancy complex. Atom probe tomog. shows a magnesium incorporation of 5%, which is substantially present at the grain boundaries of the Cu2O.

The article was titled 《Precursor to Gas Sensor: A Detailed Study of the Suitability of Copper Complexes as an MOCVD Precursor and their Application in Gas Sensing》.Recommanded Product: Bis(acetylacetone)copper The article contains the following contents:

There are very few p-type semiconductors available compared to n-type semiconductors for pos. sensing response for oxidizing gases and other important electronic applications. Cupric oxide (CuO) is one of the few oxides that show p-type conductivity, useful for sensing oxidizing gases. Many researchers obtained CuO using the chem. and solid-state routes, but uniformity and large-area deposition have been the main issues. Chem. vapor deposition is one such technique that provides control on several deposition parameters, which allow obtaining thin films having crystallinity and uniformity over a large area for the desired application. However, CuO-chem. vapor deposition (CVD) is still unfathomed due to the lack of suitability of copper precursors based on vapor pressure, contamination, and toxicity. Here, to address these issues, we have taken four Cu complexes (copper(II) acetylacetonate, copper(II) bis(2,2,6,6-tetramethyl-3,5-heptanedionato), copper(II) ethylacetoacetate, and copper(II) tert-butylacetoacetate), which are evaluated using thermogravimetry for suitability as a CVD precursor. The decomposition behavior of the complexes was also exptl. confirmed by depositing CuO thin films via CVD. Phase purity, decomposition, volatility, growth rate, and morphol. characteristics of the films are investigated in detail. Anal. suggests that copper(II) tert-butylacetoacetate has the highest vapor pressure and growth rate at a low temperature, making it the most suitable precursor for high-throughput CVD. Further, to investigate the role of these precursors, films deposited using Cu complexes were subjected to gas sensing. The CuO gas sensor fabricated on glass shows pronounced NO2 sensing. The sensing results of CuO films have been explained from the standpoint of roughness, morphol., and unpassivated bonds present on the surface of films and vapor pressure of precursors. The higher d. of surface state and the lower resistivity of the Cu(tbaoac)2 film lead to a sensor with higher responsivity and sensitivity (down to 1 ppm). These precursors can probably be utilized to improve the performance of other metal oxide gas sensors, especially Cu2O and Cu-III-O2.

《Ligand-Guided Growth of Alloyed Shells on Intermetallic Seeds as a Route toward Multimetallic Nanocatalysts with Shape-Control》 was written by Bueno, Sandra L. A.; Gamler, Jocelyn T. L.; Skrabalak, Sara E.. Recommanded Product: 13395-16-9 And the article was included in ChemNanoMat in 2020. The article conveys some information:

Shape-controlled core@shell PdCu@PtCu nanoparticles (NPs) were synthesized by seed-mediated co-reduction Specifically, cubic-shaped NPs were achieved by selecting tetraoctylammonium bromide (TOAB) and triphenylphosphine (TPP) as capping ligands. Their roles were investigated by incorporating independently each ligand into the reaction and analyzing the products by transmission electron microscopy (TEM). This anal. revealed that the quasi-spherical PdCu seeds acquired cubic shapes during the synthesis and directed shell deposition. This process was mediated by TPP, which was central to achieving monodisperse NPs with shape-control. The synthesis conditions were modified to tune both the thickness and composition of the shells. Evaluation of the NPs as catalysts for the electrooxidation of formic acid found that the NPs with the thinnest Pt-rich shells gave the highest specific activity, with the nanocubic shape also enhancing performance with respect to the spherical counterpart. These results highlight the benefits of integrating compositional, architectural, and shape-control all in one NP construct.Bis(acetylacetone)copper(cas: 13395-16-9Recommanded Product: 13395-16-9) was used in this study.
