Metallic NiFe as Bifunctional Electrocatalysts for Efficient Urea Conversion

摘要

A simple electrodeposition method was used to prepare metallic NiFe on nickel foam(NiFe/NF).NiFe/NF showed excellent electrocatalytic activities for HER and UOR in an alkaline solutioncontaining urea. The electrochemically active surface area(ESCA) measurements indicating thatNiFe/NF has an improved ESCA and more active sites. Metallic NiFe can be used as a bifunctionalcatalyst for efficient urea oxidation and electrocatalytic hydrogen evolution..
