Single-atom iron doped BiOCl atomic layers to promote efficient CO2 electroreduction towards formate

Abstract

The electrocatalytic CO₂ reduction reaction to valuable fuels is a promising strategy to simultaneously tackle the crises of fossil fuel shortage and carbon emission. Herein, a single-Fe-atom was introduced into the BiOCl catalyst by a facile hydrolysis method, which exhibited a greatly enhanced catalytic performance in the electrochemical CO₂RR to formate, exceeding 90% hydrogenation selectivity and maintaining above 90% activity for 10 hours.
