MOF-808/Bi2WO6光催化剂的构筑及其光催化性能研究
PREPARATION AND PHOTOCATALYTIC PROPERTIES OF MOF-808/Bi2WO6 COMPOSITES
摘要
Abstract
In this paper,MOF-808/Bi2WO6 composite photocatalytic materials with different proportions were successfully constructed by hydrothermal method.A series of characterization methods were used to characterize the composites.Using Rhodamine B(RhB)as the target pollutant for degradation,the difference of photocatalytic performance of MOF-808/Bi2WO6 with different proportions was investigated.The results show that 20％-MOF-808/Bi2WO6 composite photocatalyst has the best degradation effect on RhB,and the degradation rate after 60 min is increased by 25％compared with pure Bi2WO6,and the photocatalytic performance is significantly improved.The cyclic experiment showed that the degradation rate of RhB was not significantly reduced after repeated use for 5 times,so the photocatalyst had good stability.It can be concluded from the free radical trapping experiment that hole(h+)plays a major role in the catalytic process,hydroxyl radical(·OH)plays a certain synergistic role in the catalytic process,and superoxide radical(·O2-)has almost no influence on the catalytic process.关键词
