Graphene aerogel-supported NiFe alloy for efficient anion exchange membrane water electrolysis

Abstract

A disordered NiFe alloy anchored on a graphene aerogel is rapidly synthesized via a microwave-assisted route. The three-dimensional open architecture enables efficient alkaline oxygen evolution and delivers stable performance in an anion exchange membrane water electrolyzer, underscoring the importance of support architecture in translating intrinsic activity to device performance.
