中文摘要:
      通过水热法成功构建具有不同比例的MOF-808/Bi2WO6复合型光催化材料,运用多种表征手段对材料的物理和化学性质进行分析表征。以罗丹明B(RhB)作为被降解的目标污染物,探究不同比例MOF-808/Bi2WO6的光催化性能差异性。实验结果表明,复合材料可以显著提高其光催化性能,其中,20%-MOF-808/Bi2WO6复合型光催化剂光催化降解效果尤为明显,可见光下反应60 min后,相对于纯Bi2WO6,其降解率提高了25%,显著提升其光催化性能。通过催化剂的再生-循环实验可知,复合材料光催化剂在五次再生-循环实验后光催化效果并无明显降低,因此该光催化剂具有良好的稳定性。经自由基捕获实验可以得出,空穴(h+)在催化过程中是主要的活性物质,羟基自由基(·OH)在催化过程中起到了一定的协同作用,而超氧自由基(·O2-)在催化过程中几乎没有贡献。
英文摘要:
      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.
