摘要
以复合表面活性剂为模板剂,微波法制得铋掺杂WO3光催化剂。采用XRD、TEM和DRS等手段对所得样品分别进行表征。结果表明:微波加热所得的样品具有更好的介孔结构,且分散更加均匀。以苯酚为模拟废水,考察催化剂用量、反应温度、溶液pH值和铋掺杂量对苯酚光催化降解效果的影响。
Porous Bi2O3/W03 composite photocatalysis is prepared by using composite surfactan as templatedirecting agent by microwave. The structure and morphological characteristics of the Bi2O3/WO3 are characterized by XRD,TEM and UV-Vis techniques. Experimental results show that the composite photocatalysis prepared by microwave enjoys good porous structure, and easily-controlled aggregation.The following photochemistry-related factors, such as photocatalyst quantity, degradation temperature, the solution＇s PH value and Bi-doping quantity, are also investigated.
