Synthesis and Characterization of ZnO-CeO2 Nanocomposite with Enhanced UV-Light-Driven Photocatalytic Dye Degradation of Rhodamine-B.

ZnO-CeO2 nanocomposite was synthesized by co-precipitation and reverse micelle methods, which show rod-shaped morphologies. In co-precipitation method, the nanocomposite has uniform rodshaped structure, whereas in reverse micelle method rods like structures are made up of spherical shaped nanoparticles. The photocatalytic dye degradation of rhodamine-B (RhB) has been examined using ZnO-CeO2 nanocomposite at room temperature. The photodegradation rates of catalysts in co-precipitation and reverse micelle methods were observed as 0.026 min-1 and 0.042 min-1, respectively.
