Photocatalytic hydrogen generation from water splitting is regarded as a sustainable technology capable of producing green solar fuels. However, the low charge separation efficiencies and requirement lowering redox potentials are unresolved challenges. Herein, multiphase copper-cuprous oxide/polypyrrole (PPy) heterostructure has been designed to identify role multiple oxidation states metal oxides in reduction oxidation. The presence mixed phase PPy heterostructures enabled an exceptionally...

Solar-to-hydrogen (H2) conversion is one of the sustainable and renewable approaches to mitigate ever-increasing environmental pollution global energy crisis. Despite significant progress, most critical aspect remains design highly efficient stable photocatalysts. Although ZnO-based photocatalysts exhibit high catalytic activity, they suffer from intrinsic drawback broadband gap with ultraviolet (UV) light absorption are susceptible oxidation. Herein, a strategy extend harvesting in visible...
1-Alkyl-2-(arylazo)imidazoles (p-R-C6H4-N=N-C3H2N2X, abbreviated as RaaiX, R = H(a), CH3(b), Cl(c); X N(1)-CH3 (1), N(1)-CH2-C6H5 (2)) have been reacted with (NH4)2[OsCl6] and OsCl2(RaaiX)2 species isolated in two isomeric forms, blue-violet (3, 5) red-violet (4, 6). IR spectra show x (Os-Cl) modes support a cis-OsCl2 configuration. X-ray diffraction methods were used to determine structures of isomers. In terms the three coordination pairs around Os(II), Cl, N, N (N(imidazole), N) N', N'...
