Bismuth-based electrocatalytic scheme enabling efficient and selective electrosynthesis of 4-aminophenol in acidic media

Abstract

A highly efficient electrocatalytic platform based on the in-situ formed metallic bismuth submicron crystals (microBi) was developed for 4-aminophenol electrosynthesis via the electrochemical reduction of 4-nitrophenol at acidic pH. The facile formation and high reactivity of microBi enable efficient electrosynthesis of 4-aminophenol with high selectivity (~100%) at the expense of an ultra-low overpotential.
