NiCoP/NiOOH nanofowers loaded on ultrahigh porosity Co foam for hydrogen evolution reaction under large current density
文献摘要：
Developing user-friendly electrodes for efficiently producing hydrogen from water to substitute non-renewable fossil fuels is one of the challenges in the hydrogen energy field.For the first time,we have prepared self-supporting ultrahigh porosity cobalt foam loaded with NiCoP/NiOOH nanoflowers(NiCoP/CF)via freeze-drying and phosphorization.The as-prepared hierarchical NiCoP/CF electrodes showed superior catalytic activity for hydrogen evolution reaction(HER)in alkaline media.The one resulted from phosphorization at 350℃(NiCoP/CF-350)only required overpotential of-47,and-126 mV to deliver geometrical current density of-10 mA cm-2 and-100 mA cm-2,respectively,demonstrating improved catalytic activity than the electrodes prepared using a commercial nickel foam as a support.Moreover,it could retain its superior stability at a current density higher than-500 mA cm-2for 16 h.Such an outstanding performance can be attributed to the ultrahigh porosity of Co foam support,optimal adsorption energies of HER intermediates(H*),facile water dissociation on the NiCoP/NiOOH hetero-interfaces,and the assistance of NiOOH facilitating the electrons transfer from the Co foam inside to the NiCoP outside.The work would provide a new strategy for future design of advanced HER electrocatalysts.
