本申请属于光催化技术领域,具体涉及一种BiOBr/CeCO3OH光催化剂及其制备方法和应用。该方法将二水合六水硝酸铈、尿素和聚乙烯吡咯烷酮溶于去离子水中,超声,搅拌,然后移入高压反应釜中,置于160℃的鼓风干燥箱内进行热处理24h冷却,洗涤,干燥,得到CeCO3OH;将五水合硝酸铋和溴化钠溶于水中,搅拌,然后加入CeCO3OH,超声,得到前驱体溶液,移入高压反应釜中进行水热处理,冷却,抽滤,洗涤,干燥,得到所述BiOBr/CeCO3OH光催化剂。本发明采用简单的溶热法在BiOBr上引入CeCO3OH,构建富含电子羟基的异质结复合材料,提高CO2还原能力,加快电子空穴分离效率,提出了一种创建富电子基团异质结的直接方法。
