摘要：
In this study, photoelectrochemical water oxidation with a hematite (alpha-Fe2O3) photoanode and electrochemical CO2 reduction with a boron-doped diamond (BDD) cathode were combined to convert CO2 into formic acid under 1 sun AM 1.5 simulated solar light irradiation. The faradaic efficiency of formic acid production by solar light-assisted CO2 reduction reached 62% and the electrical-to-chemical energy conversion efficiency was 46%. The photo-assisted electrolysis efficiency reached 0.37%.
