Electrocatalytic CO2 reduction (CO2ER) to produce formic acid (HCOOH) would be an attractive means for carbon neutralization. In order to realize efficient CO2ER and economical conversion of CO2, the applying of metal active sites on surface of semiconductor has emerged as a promising strategy. Herein, we report the preparation of alkaline modified TiO2 nanowires (NWs) as the substrate for Au photodeposition. The asfabricated Au/TiO2 NWs exhibits high activity and selectivity towards HCOOH production compared with traditional catalysts. The key factors including deposition time, solution, and ...
