Fe2P nanoparticles embedded on Ni2P nanosheets as highly efficient and stable bifunctional electrocatalysts for water splitting
文献摘要：
It is urgent to develop highly efficient,stable and low-cost bifunctional electrocatalysts for overall water splitting.Herein,an iron-nickel phosphide(Fe2P/Ni2P)heterostructure,constructed by Fe2P nanoparticles embedded on Ni2P nanosheets,is strategically fabricated on nickel foam via a facile process.As a bifunc-tional electrocatalyst,the Fe2P/Ni2P heterostructure delivers a very low overpotential of 64 mV(or 185 mV)to reach current density of 10 mA cm-2 for hydrogen(or oxygen)evolution reaction.When simulta-neously employed as both the anode and cathode electrodes,it demonstrates an ultralow cell voltage of 1.49 V@10 mA cm-2 for full water splitting with nearly 100％Faradaic efficiency,and superior long-term stability even over 100 h.Density functional theory calculations manifest that a strong heterointerface in-teraction could cause electron redistribution near the Fe2P/Ni2P heterointerface and optimize the ΔGH-of P sites,thus enhancing catalytic activity.Additionally,the 3D porous heterostructure is benefit to expose rich active sites and facilitate ion diffusion and gas bubble release,thus promoting the catalytic perfor-mance.This work opens up a new strategical approach for rational design of metal phosphide-based heterostructures as highly efficient and stable bifunctional electrocatalysts for water splitting.
