Sulfur-doped BiOCl prepared by a simple hydrothermal method exhibited excellent photocatalytic performance with an expanded light absorption range and significantly increased visible-light photocatalytic water oxidation rate.
Photocatalysis is a powerful strategy to address energy and environmental concerns. Sulfur-doped BiOCl was prepared through a facial hydrothermal method to improve the photocatalytic performance. Experimental results and theoretical calculations demonstrated that the band structure of the sulfur-doped BiOCl was optimally regulated and the light absorption range was expanded. It showed excellent visible-light photocatalytic water oxidation properties with a rate of 141.7 mu mol h(-1) g(-1) (almost 44 times of that of the commercial BiOCl) with Pt as co-catalyst.
