摘      要：Judiciously engineering the electrocatalysts is attractive and challenging to exploit materials with high electrocatalytic performance for hydrogen evolution reaction.Herein,we successfully perform the interface engineering by alternately depositing Co±P and Ni±Fe±P films on nickel foam,via facile electroless plating and de-alloying process.This work shows that there is a significant effect of de-alloying process on alloy growth.The electronic structure of layered alloys is improved by interface engineering.The multilayer strategy significantly promotes the charge transfer.Importantly,the Co±P/Ni±Fe±P/NF electrode fabricated by interface engineering exhibits excellent electrocatalytic hydrogen evolution activity with an overpotential of 43.4 mV at 10 mA cm^(-2)and long-term durability for 72 h in alkaline medium(1 mol L^(-1)KOH).The innovative strategy of this work may aid further development of commercial electrocatalysts.
