Abstract

In this study, we have facilely developed a SnO₂-based electrocatalyst (SnO₂-V_O@N–C), which can combine together the favorable structure features of oxygen vacancies, porosity, and full-coating with N-doped carbon layers (N–C). Our experimental and theoretical calculation results indicated that with the facile engineering of oxygen vacancies and the full-coating of the N-doped carbon layer, the adsorption/activation of CO₂ and charge transfer can be promoted in the CO₂ reduction process, making SnO₂-V_O@N–C the electrocatalyst with improved activity and selectivity (FE_HCOOH = 84%) toward the reduction of CO₂ to HCOOH.
