Photocatalytic degradation of rohdamine B by modified zinc oxide catalysts

Abstract

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).
