  • Key Words:HYDROGEN EVOLUTION REACTION
  • Abstract:Heterogeneous structure supported Ni-Fe-P-Ni(OH)(2)/NF catalysts were fabricated by electroless deposition. The as-prepared composite catalyst exhibits remarkable electrocatalytic properties towards the hydrogen evolution reaction, requiring a low overpotential of 201 mV at a current density of -100 mA cm(-2). Notably, the Ni-Fe-P-Ni(OH)(2)/NF also demonstrates exceptional oxygen evolution performance, achieving a current density of 100 mA cm(-2) with only 294 mV overpotential. Moreover, its performance in overall water splitting, serving as both a cathode and an anode, showcases a significantly low overpotential of 1.51 V at a current density of 10 mA cm(-2). Following a 24-hour chronopotentiometry stability test at a current density of 50 mA cm(-2), the dual electrodes maintain excellent performance for overall water splitting. This work provides a feasible method for the research and development of efficient and stable overall water splitting catalysts.
