A strategy is proposed for modifying BiVO4 photoanode with CoNiO2 as a novel water oxidation cocatalyst to enhance PEC water splitting performance. The results show that CoNiO2 has the following functions: reducing photogenerated charge recombination centers; providing trapping sites to promote charge separation; improving the stability of the overall system; providing more active sites; and offering a lower overpotential. The BiVO4/CoNiO2 photoanode has a higher photocurrent density (1.16 mA cm−2 at 1.23 V vs. RHE), a lower onset potential (∼0.06 V vs. RHE), a larger IPCE (34.37%) and ABPE (0.163%), better stability and good rates of hydrogen evolution (0.0148 μmol cm−2 min−1) and oxygen evolution (0.0076 μmol cm−2 min−1). The strategy provides promising prospects for achieving efficient PEC water splitting performance using water oxidation cocatalysts. [ABSTRACT FROM AUTHOR]

A novel coordination polymer has been synthesized using an anthracene-based linker, and the photocatalytic properties of this visible-light-responsive compound are evaluated where it shows highly selective photooxidation of sulfides to produce sulfoxides relying on reactive species of singlet oxygen.

An efficient palladium-catalyzed oxidative aminocarbonylation of azoles has been developed. This system allows for intermolecular carbonylative cross-coupling of aromatic C(sp2)–H bonds with simple amines, which has often been asked for, but has not been realized so far. It provides a straightforward approach to a variety of azol-2-amides. [ABSTRACT FROM AUTHOR]

An unprecedented catalyst-free formylation of amines using CO2 and hydrosilanes was developed. The solvent plays a vital role in promoting the interaction of amines with hydrosilanes and subsequent CO2 insertion, thus facilitating the simultaneous activation of N–H and Si–H bonds. Based on relevant mechanistic studies, a plausible mechanism involving a silyl carbamate intermediate is proposed. [ABSTRACT FROM AUTHOR]
