近期，我院教师李阳，硕士研究生罗凯的研究成果“Flexible cupric oxide photocathode with enhanced stability for renewable hydrogen energy production from solar water splitting”在《Royal Society of Chemistry Advances》上发表。
论文简介如下：
Copper oxide (CuO) is a promising but unstable photocathode in solar water splitting. Herein, a flexible CuO photocathode is prepared and its degradation mechanisms and stabilization strategies have been discussed. Briefly, we find alkali environment and low light intensity are the critical factors in the stabilization of the CuO photocathode. For practical usage, a composite semiconductor layer, composed of TiO2, La2O3 and NiO, is deposited on the CuO photocathode, which is proved to be effective for enhancing the stability of the CuO photocathode. 100% of the photocurrent density has been retained after 20 minutes of continuous illumination. The optimized stable photocurrent density is measured as 0.3 mA cm−2 at 0.5 VRHE.
