Understanding the electrocatalytic mechanism of self-template formation of hierarchical Co₉S₈/Ni₃S₂heterojunctions for highly selective electroreduction of nitrobenzene

Abstract

interface, which markedly reduces the energy barrier for reduction of nitrobenzene to aniline. This work offers a successful example for the interfacial engineering of metal sulfide-based heterojunctions with excellent electrocatalytic nitroarene reduction performance, and also paves the way for the in-depth understanding of the corresponding mechanism.
