Hydrogen evolution and oxidation are critical to realizing hydrogen energy recycling and to the hydrogen economy. Therefore, it is important to develop non-precious metal catalysts with high efficiency and stability for the hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR). In this study, we reported on the facile synthesis of Co2P-Fe2P heterogeneous nanoparticles on a porous carbon skeleton (Co2P-Fe2P/C), which exhibited high activity for both HOR and HER in alkaline conditions. The overpotential of Co2P-Fe2P/C toward HER was 77 mV at 10 mA cm-2, with a Tafel slope of 42...
