摘要

采用MCM-41改性ZnO作为光催化剂，在紫外可见光下对罗丹明B等有机污染物水溶液进行光降解，具有成本低、利用太阳光、反应条件温和、光化学反应活性高、环境毒性低、光腐蚀稳定性好等优点。采用沉淀法制备了不同MCM41/ZnO含量(1%、3%、5%、8%)的ZnO光催化剂和MCM-41/ZnO光催化剂。合成了纳米复合材料，并用x射线衍射(XRD)对其进行了表征。

Photocatalytic degradation of rohdamine B by modified zinc oxide catalysts

Aqueous solutions of organic contaminant like rhodamine B) is photodegraded under ultraviolet visible light using modified ZnO by MCM-41 as photocatalyst, due to its low costs, use of sunlight, mild reaction conditions, high photochemical reactivity, low environmental toxicity and stability to photocorrosion. ZnO and MCM-41/ZnO photocatalysts with different percentage of MCM41/ZnO (1%, 3%, 5%, and 8%) were prepared by precipitation method. Nanocomposites was synthesized and characterized by X-ray diffraction (XRD).
