Abstract
Due to its unique layered structure, bismuth oxychloride (BiOCl) has potential applications as a photocatalytic material in clean energy utilization and environmental purification. In recent years, researchers have carried out a lot of studies and made important progress for the preparation and performance enhancement of BiOCl. In this review, the charge separation property of BiOCl was analyzed based on the crystal structure and electronic structure. Subsequently, the common preparation method of BiOCl was expounded, and the growth mechanism of BiOCl was introduced. Furthermore, the strategies for modulating the photocatalytic performance of BiOCl via doping, vacancy creation, internal electric field tuning, co-catalysts modification, composites construction and sensitizers using were summarized. Finally, in view of the current research status of BiOCl photocatalytic material, some problems still need to be addressed include exploring the method of controlled synthesis of other high energy surface BiOCl, developing advanced characterization methods to clarify the detailed transfer path of photogenerated charge and expanding the photocatalytic application range of BiOCl.
