采用H2-O2火焰快速退火法制备了一种在铜箔表面覆盖一层氧化铜（CuO）的p型氧化亚铜（Cu 2 O）光电阴极。所制备的复合光电阴极的特征在于在Cu 2 O的（110）面和CuO的（111）面之间形成的结结构。通过增加CuO在Cu 2 O上的覆盖度，Cu 2 O/CuO复合光电阴极的光电化学（PEC）水还原稳定性得到改善。
A p-type cuprous oxide (Cu2O) photocathode covered with a thin layer of cupric oxide (CuO) was prepared by fast annealing of a copper foil via H-2-O-2 flame. The as-prepared composite photocathode is characteristic of a junction structure formed between the (110) plane of Cu2O and the (111) plane of CuO. The Cu2O/CuO composite photocathode showed improved stability for photoelectrochemical (PEC) water reduction by increasing the coverage of CuO on Cu2O.
