Sb2S3-templated synthesis of sulfur-doped Sb-N-C with hierarchical architecture and high metal loading for H2O2 electrosynthesis

Abstract

Selective two-electron oxygen reduction reaction is critical electrochemical process for H2O2 electrosynthesis. Here, the authors develop a Sb2S3-templated strategy to fabricate high-density atomic dispersion of Sb on N,S-codoped hollow carbon nanofiber substrate, which facilitate with the improved selectivity, catalytic mass activity and production rate of H2O2.
