| 摘 要： | 在空气氛围下,900℃热解硼酸-三聚氰胺前驱体制备多孔氮化硼(PBN),然后通过原位沉淀法制备出Ag3PO4/PBN复合光催化剂。利用X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱(UV-Vis DRS)、荧光分光光度计(PL)等方法对复合物的结构和形貌进行分析。以罗丹明B(RhB)为降解底物,对光催化性能进行评价。使用异丙醇(PA)、乙二胺四乙酸二钠(EDTA-2Na)、对苯醌(BQ)和AgNO3捕获.OH、h+、.O2-和e-,对光催化机理进行研究。结果表明, Ag3PO4/PBN在PBN含量为70mg时催化效果最好,在可见光照射10min后,0.03g复合光催化剂对RhB溶液(50ml,30mg/L)降解率达到99.6%,具有优良的降解性能；3次重复实验后,催化剂的催化性能几乎没有发生变化,.OH、h+和.O2-在Ag3PO4/PBN光催化降解过程中起主要作用。
