Summary: As a typical two-dimensional layered material, MoS2 has attracted extensive attention due to its adjustable electronic structure, abundant reserves, and excellent chemical stability. This study synthesized g-C3N4/Fe3O4/MoS2 composite electrocatalysts by growing MoS2 nanosheets on Fe3O4 sites supported on g-C3N4 substrates. The results showed that Fe3O4 sites facilitated the dispersion of MoS2 nanosheets, leading to high exposure of catalyst active sites, redistribution of surface charge, and optimization of hydrogen adsorption kinetics and stability.

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.
