Abstract
Here we report a self-supported SnO2 nanofilm prepared by a robust electrochemical process as an electrocatalyst for the CO2 reduction reaction. The SnO2 film had a large surface area originating from its nano-architecture and manifested high selectivity toward formate (over 60%), which resulted in CO2-to-formate current density up to 33.66 mA cm(-2) that is among the state-of-the-art. We unveiled that the high performance of the SnO2 nanofilm is attributable to the presence of a metastable oxide under reductive conditions in addition to the abovementioned advantages.
