Abstract:We identify the function of CuO impurities in CuBi 2 O 4 photocathodes significantly improving the photoelectrochemical water reduction efficiency. Spectroelectrochemical photo/voltage-induced absorption spectroscopies are employed to investigate the charge carrier dynamics of pure, CuO-impure, and CuO-covered CuBi 2 O 4 photocathodes during photoelectrochemical water reduction, in comparison with the CuO/FTO for electrochemical water reduction. Electrons after photoexciation are found to accumulate at the sur… Show more
