Summary: NiCo2O4 nanowire array on carbon cloth (NiCo2O4/CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3-) reduction to ammonia (NH3). It achieves a high Faradic efficiency of 99.0% and a large NH3 yield up to 973.2 mu mol h(-1) cm(-2). The superior catalytic activity comes from its half-metal feature and optimized adsorption energy due to the existence of Ni in the crystal structure.

Summary: Electrocatalytic hydrogen peroxide synthesis via two-electron oxygen reduction reaction pathway is becoming increasingly important due to its green production process. Introducing cationic vacancies on nickel phosphide as a proof-of-concept to regulate the catalyst's properties has led to efficient H2O2 electrosynthesis. The created Ni cationic vacancies enriched Ni2-xP-V-Ni electrocatalyst exhibits remarkable 2e ORR performance and long-term durability, with optimized geometric and electronic structures. Cation vacancy engineering is believed to be an effective strategy for creating active heterogeneous catalysts with atomic precision.

Summary: The development of bifunctional water-splitting electrocatalysts that are efficient and stable over a wide range of pH is crucial but challenging. This study reports an atomically dispersed Ru/Co dual-sites catalyst anchored on N-doped carbon (Ru/Co-N-C) for excellent oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in both acidic and alkaline electrolytes. The catalyst shows superior performance compared to benchmark catalysts Pt/C and RuO2, with low overpotentials and high current densities. Theoretical calculations and experimental results demonstrate that the introduction of Co-N4 sites into Ru/Co-N-C modifies the electronic structure of Ru and enhances the bonding strength with oxygen/hydrogen intermediate species, leading to improved OER and HER performance. Furthermore, the incorporation of Co-N4 sites improves the corrosion-resistance of Ru/Co-N-C during electrolysis. The Ru/Co-N-C catalyst has been successfully applied in a proton exchange membrane water electrolyzer and shows stable operation at a high current density.
