Electrochemical (EC) CO2 reduction is a promising method to convert CO2 into valuable hydrocarbon fuels and chemicals ecofriendly. Here, we report on a facile method to synthesize surface-controlled SnO2/Cu(OH)2 nanowires (NWs) and its EC reduction of CO2 to HCOOH and CO. The SnO2/Cu(OH)2 NWs (-16 mA/cm2 ) showed superior electrochemical performance compared to Cu(OH)2 NWs (-6 mA/cm2 ) at -1.0 V (vs. RHE). SnO2/Cu(OH)2 NWs showed the maximum Faradaic efficiency for conversion to HCOOH (58.01 %) and CO (29.72 %). The optimized catalyst exhibits a high C1 Faradaic efficiency stable electrolysis for 2 h in a KHCO3 electrolyte. This study facilitates the potential for the EC reduction of CO2 to chemical fuels.
