Preparation of Zno-Cr₂O₃ Composites by a Sol-Gel Method and their Photocatalytic Activities

Abstract:

The ZnO-Cr2O3 composites with different complex proportion were prepared by a sol-gel method. The mol ratio of Zn and Cr element could be tuned by controlling the concentration of the precursors. These composites showed photocatalytic activities in degradation of methyl orange under the irradiation of 300W mercury lamp. And the activities regularly varied with the mol ratio of Zn and Cr. When n（Zn）:n（Cr）=10:1, a composite with best photocatalytic activity could be obtained.
