将载有RuO_2的半导体CdS催化剂粉末悬浮在Na_2S水溶液中,用可见光照射,光解产生H_2。研究了催化剂上RuO_2载量、焙烧温度以及浸渍次数等因素对催化剂活性的影响。进一步提高了RuO_2/CdS的催化活性。
The semiconductor CdS catalyst powder containing RuO_2 is suspended in a Na 2 S aqueous solution and irradiated with visible light to generate H 2 by photolysis. The effects of RuO 2 loading, calcination temperature and impregnation times on the catalyst activity were investigated. Further improving the catalytic activity of RuO 2 / CdS.
