Abstract: A new kind of photocatalytic materials based on bismuth oxychloride (BiOCl) has received much attention owing to its inherent layer structure and particular electronic characteristics，and BiOCl-based materials exhibit the excellent photocatalytic activities and potential practical prospects in energy utilization，environmental protection，chemical application，material fields，and so on. The crystal and electronic structures of BiOCl semiconductor were first investigated. Then recent research and development in the preparation methods，structure morphologies，visible-light response and immobilization of BiOCl-based materials have been comprehensively reviewed and analyzed; meanwhile the obtained correlative photocatalytic mechanisms for certain BiOCl-based catalysts based on first-principles calculations were also summarized. The promising research trends of BiOCl-based photocatalytic materials，such as the relative deposition on suitable substrate surface，the effect mechanism between catalysts and absorbable organics on the surface，photocatalytic reaction mechanism，have been prospected.
