Abstract Doping with pyridinic nitrogen atoms is known as an effective strategy to improve the activity of carbon-based catalysts for oxygen reduction reaction. However, prefer occupy at edge or defect sites carbon materials. Here, a framework named hydrogen-substituted graphdiyne provides suitable matrix doping. In graphdiyne, three in benzene ring are bonded hydrogen and serve active sites, like positions conventional materials, on which can be selectively doped. The as-synthesized...
Superefficient water-splitting materials comprising sub-nanometric copper clusters and quasi-amorphous cobalt sulfide supported on foam are reported. While working together at both the anode cathode sides of an alkaline electrolyzer, this material gives a catalytic output overall water splitting comparable with Pt/C–IrO2-coupled electrolyzer. As service to our authors readers, journal provides supporting information supplied by authors. Such peer reviewed may be re-organized for online...
Lead-free perovskite nanocrystals (NCs) were obtained mainly by substituting a Pb2+ cation with divalent or three cations two trivalent cations. The substitution of one monovalent Ag+ and Bi3+ was used to synthesize Cs2 AgBiX6 (X=Cl, Br, I) double NCs. Using femtosecond transient absorption spectroscopy, the charge carrier relaxation mechanism elucidated in AgBiBr6 NCs exhibit ultrafast hot-carrier cooling (<1 ps), which competes trapping processes (mainly originate from surface defects)....

A combined theoretical and experimental study that reveals periodic in electrocatalytic activity hydrogen evolution reaction (HER) from Group IV B to VIII metal diborides reported here. Theoretical results demonstrate a general linear relationship between d ‐band center diboride, meaning...
In order to address an all-inorganic halide lead-free perovskite for potential photovoltaic applications, we carried out first-principles calculations of bandgaps 260 perovskites belonging the class ABX3, with A = Li, Na, K, Rb, Cs, B Pb, Sn, and Ge, X F, Cl, Br, I. Three most common crystal symmetries were chosen, including cubic, tetragonal, two orthorhombic phases. The bandgap exhibited increase decreasing anions radius (I, F) lowering symmetry structures. With consideration multiple...
The cation substitutional doping of metal oxide semiconductors plays pivotal roles in improving the gas sensing performances, but effect on surface reaction is still not well understood.
