Synthetic Route of 13395-16-9, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, once mentioned the application of Synthetic Route of 13395-16-9, Name is Bis(acetylacetone)copper,molecular formula is C10H16CuO4, is a conventional compound. this article was the specific content is as follows.

Addressed herein is the composition-controlled catalysis of CuPd alloy nanoparticles (NPs) supported on reduced graphene oxide (RGO) in the hydrolytic dehydrogenation of ammonia borane (AB). Nearly monodisperse CuPd alloy NPs were synthesized by using a surfactant-assisted organic solution phase protocol comprising the co-reduction of acetylacetonate complexes of Pd and Cu by morpholine borane complex in oleylamine and 1-octadecene at 80 C. The presented recipe allowed us to make a composition control over the CuPd alloy NPs. Three different compositions of CuPd alloy NPs (2.7 nm Cu30Pd70, 2.9 nm Cu48Pd52, 3.0 nm Cu75Pd25) could be prepared among which the Cu75Pd25 NPs showed the best catalytic performance in hydrogen generation from the hydrolysis of AB. Among the various support materials tested for as-prepared Cu75Pd25 alloy NPs, the RGO-Cu75Pd25 catalysts showed the highest performance in the hydrolysis of AB. Moreover, the activity of the RGO-Cu75Pd25 catalysts were dramatically enhanced by annealing them at 400 C for 1 h under Ar-H2 (5% H2) gas flow and an unprecedented TOF value of 29.9 min-1 was obtained in the hydrolysis of AB at room temperature. The reported TOF value here is much higher than RGO-Cu (TOF = 3.61 min-1) and even higher than RGO-Pd catalysts (TOF = 26.6 min-1). The detailed kinetics of RGO-Cu75Pd25 catalyzed AB hydrolysis was also studied depending on catalyst concentration, substrate concentration and temperature. The apparent activation energy of the catalytic hydrolysis of AB was calculated to be 45 ± 3 kJ mol-1.

Dye molecules bonded to a semiconductor surface could inject carriers to a band on photoexcitation. This process known as dye-sensitization is used for extending the sensitivity of silver halide emulsions. More recently, dye-sensitization has been adopted to devise solar cells. A near-infrared (NIR) sensitive heterojunction n-TiO2/D/p-CuSCN (where D denotes a NIR absorbing dye) is developed to examine the possibility of using dye-sensitization for IR detection. Although the responsivity is lower and response slow compared to silicon detectors, dye-sensitized detectors would be cost effective, especially for large area devices. They are operable at room temperature and have the advantage of insensitivity to noise induced by band-gap excitations (providing high specific detectivity of ?10 11). Furthermore, the spectral response can be adjusted by choosing the appropriate dye.

We have developed semiconductor growth techniques for the coating and filling of nanopores in ceramic-type substrates. The main idea behind this research is to use the large inner surface of ceramics as a template for the realization of semiconductor heterojunctions with extremely large interface area. As porous substrates we use lightly sintered nanocrystalline TiO2 of 5-10 mum thickness. The pore volume in these substrates is approx. 50% and the average pore diameter is 30-50 nm. We are able to establish nanometer thick coatings on the inner surfaces of these substrates or – in a different technique – fill the pore volume with (100 ± 3)% efficiency. The growth techniques involve chemical and electrochemical methods from liquid solutions. Binary, ternary and, most recently, quaternary compounds of the II-VI and I-III-VI material systems were prepared.

This study reports the development of copper(I) thiocyanate (CuSCN) hole-transport layers (HTLs) processed from aqueous ammonia as a novel alternative to conventional n-alkyl sulfide solvents. Wide bandgap (3.4?3.9 eV) and ultrathin (3?5 nm) layers of CuSCN are formed when the aqueous CuSCN?ammine complex solution is spin-cast in air and annealed at 100 C. X-ray photoelectron spectroscopy confirms the high compositional purity of the formed CuSCN layers, while the high-resolution valence band spectra agree with first-principles calculations. Study of the hole-transport properties using field-effect transistor measurements reveals that the aqueous-processed CuSCN layers exhibit a fivefold higher hole mobility than films processed from diethyl sulfide solutions with the maximum values approaching 0.1 cm2 V?1 s?1. A further interesting characteristic is the low surface roughness of the resulting CuSCN layers, which in the case of solar cells helps to planarize the indium tin oxide anode. Organic bulk heterojunction and planar organometal halide perovskite solar cells based on aqueous-processed CuSCN HTLs yield power conversion efficiency of 10.7% and 17.5%, respectively. Importantly, aqueous-processed CuSCN-based cells consistently outperform devices based on poly(3,4-ethylenedioxythiophene) polystyrene sulfonate HTLs. This is the first report on CuSCN films and devices processed via an aqueous-based synthetic route that is compatible with high-throughput manufacturing and paves the way for further developments.

Halide double perovskites based on combinations of monovalent and trivalent cations have been proposed as promising lead-free alternatives to lead halide perovskites. Among the newly synthesized compounds Cs2BiAgCl6, Cs2BiAgBr6, Cs2SbAgCl6, and Cs2InAgCl6, some exhibit bandgaps in the visible range and all have low carrier effective masses; therefore, these materials constitute potential candidates for various opto-electronic applications. Here, we use first-principles calculations to investigate the electronic properties of the surfaces of these four compounds and determine, for the first time, their ionization potential and electron affinity. We find that the double perovskites Cs2BiAgCl6 and Cs2BiAgBr6 are potentially promising materials for photo-catalytic water splitting, while Cs2InAgCl6 and Cs2SbAgCl6 would require controlling their surface termination to obtain energy levels appropriate for water splitting. The energy of the halogen p orbitals is found to control the conduction band level; therefore, we propose that mixed halides could be used to fine-tune the electronic affinity.

Three novel Zn(II) complexes, [ZnCl2(qz)2] (1), [ZnCl2(1,5-naph)]n (2) and [ZnCl2(4,7-phen)2] (3), where qz is quinazoline, 1,5-naph is 1,5-naphthyridine and 4,7-phen is 4,7-phenanthroline, were synthesized by the reactions of ZnCl2 and the corresponding N-heterocyclic ligand in 1:2 molar ratio in ethanol at ambient temperature. The characterization of these complexes was done by NMR, IR and UV?Vis spectroscopy, and their crystal structures were determined by single-crystal X-ray diffraction analysis. Complexes 1 and 3 are mononuclear species, in which Zn(II) ion is tetrahedrally coordinated by two nitrogen atoms belonging to two qz or 4,7-phen ligands, respectively, and by two chloride anions, while complex 2 is a 1D coordination polymer that contains 1,5-naph as bridging ligand between two metal ions. In agar disc-diffusion assay, complexes 1?3 manifested good inhibitory activity against two investigated Candida strains (C. albicans and C. parapsilosis), while not inducing toxic effects on the healthy human fibroblast cell line (MRC-5). This activity was not fungicidal, as revealed by the broth microdilution assay, however complex 3 showed the ability to modulate Candida hyphae formation, which is an important process during infection and showed significant synergistic effect with clinically used antifungal polyene nystatin.

Sulfur-containing nitriles have important research value in the life sciences due to their diverse biological activities resulting from the sulfur and cyano functional groups. Herein, a copper-catalyzed cyanothiolation of N-tosylhydrazones with thiocyanates to generate alpha-arylthioalkanenitriles bearing sulfur-substituted quaternary carbon center atoms has been described. This novel protocol involves the procedure of copper carbene species promoting S-CN bond cleavage and C-CN/C-S bond reconstruction to introduce both sulfur and cyano groups onto a single carbon center. This cyanothiolation reaction will greatly enhance the synthetic utility of carbenoid species as new entries for the construction of diverse heteroatom-containing nitriles via cyanofunctionalization of metal-carbene species.
