摘要

采用水热合成法制备BiOBr/g-C3N4复合光催化剂,利用扫描电镜(SEM)、X射线衍射仪(XRD)和荧光光谱仪(PL)对其进行表征。结果表明:BiOBr呈近似方形片状颗粒,边长约600nm,厚度约40nm,并且均匀地分布在g-C3N4薄片上。在可见光下,BiOBr/g-C3N4复合催化剂催化降解罗丹明B(RhB),降解率最高达96%,经过4次重复使用,其降解率仍然可达90%以上。

Abstract

BiOBr/g-C3N4 composite photocatalysts were prepared by hydrothermal method and characterized by SEM,XRD and PL methods.It was found that the BiOBr particles were approximately square flake,with edge length 600nm and thickness 40nm,and evenly distributed on the g-C3N4 thin flakes.The photocatalytic degradation rate of rhodamine B catalyzed by BiOBr/g-C3N4 was 96% after 60min visible light irradiation,and the degradation rate still reached more than 90% after four times of repeated use of the same catalyst.
