摘      要：Aiming to design and prepare non-noble metal electrocatalysts for hydrogen production at high current density(HCD),NiCoP@FeNi LDH hierarchical nanosheets were deposited on nickel foam progressively us-ing a hydrothermal-phosphorization-electrodeposition *** hydrogen evolution reaction(HER)and oxygen evolution reaction(OER),NiCoP@FeNi LDH/NF requires only 195 and 230 mV overpotentials to reach 1000 mA cm−2,*** overall water splitting,only 1.70 V is required at 1000 mA cm−*** is the largest value for non-noble metal-based electrocatalysts reported so far at *** hierarchi-cal structure exhibits good electron transport capability and the porous-macroporous structure enhances the gas release rate,resulting in enhanced hydrogen production at ***,the synergistic effect of NiCoP and FeNi LDH contributes to the adsorption-desorption equilibrium of intermediate radicals dur-ing the reaction process and ultimately enhances the catalytic *** work provides useful direction for industrial-scale hydrogen production applications at HCD.
