Degradation Of Methyl Orange

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.

Degradation Of Methyl Orange

ZnO treated at 200 °C offered high photocatalytic degradation of methyl orange (99%) in a short time (90 min). The activity can be attributed to several factors including low crystallite size, high band gap energy and porosity.
