摘要:

光電化學太陽能分解水制氫，能夠直接將太陽能捕獲、轉化、存儲為化學能，是有效應對目前能源與環境問題的方法。在光電化學分解水中，半導體光電極的性能決定了太陽能轉化效率。但是對于半導體光電極，由于存在光生載流子的復合和傳輸距離短等問題，限制了光電化學性能。因此，主要結合作者課題組和國內外其他研究組的研究，以氧化鐵、氮化鉭等半導體材料為例，從電極的形貌調控、離子摻雜以及其表面的鈍化層和過渡金屬電催化劑改性等方面，綜述了提高光電極性能的方法。

Abstract:

Photoelectrochemical (PEC) water splitting can directly capture, convert and store the solar energy into chemical energy. The solar conversion efficiency of PEC water splitting is depended on the performance of a photoelectrode. However, severe recombination and short transfer distance of photo�瞘enerated carriers in a semiconductor photoelectrode limit its conversion efficiency. In this review, we focus on introducing some methods to improve the performance of a photoelectrode, according to some recent research in our group and others’. We use the iron oxide and tantalum nitride photoelectrodes as examples to illustrate the effects of morphology control, ion doping and surface treatment on the performance of a photoelectrode.
