Tin oxide (SnOx) has emerged as a promising metal oxide catalyst for the CO2 reduction reaction (CO2RR) into value-added chemicals such as formic acid/formate. However, the improvement of SnOx catalytic performance is hindered by its complex surface structures and limited knowledge about the nature of the active sites. We discovered the critical role of oxygen vacancies (Ov) in partially reduced SnO2(110) for CO2RR selectivity by combined theoretical and experimental studies.
