Photocatalytic degradation of malachite green in aqueous solution by TiO₂-ZnO nanocomposition was studied. The characteristics of the degradation by TiO₂-ZnO nanocomposition were investigated by changes of some factors such as the initial concentration of malachite green, reaction time, pH value and light source. The photodegradation of malachite-green is related with concentration. It shows that malachite green with 10 mg·L^-1 is degraded faster than those with the concentrations of 5 mg·L^-1 and 40 mg·L^-1. When malachite green concentrations are 5 mg·L^-1 and 10 mg·L^-1, and pH is 7, the degradation rates of malachite-green are above 99% under the ultraviolet radiation only in 30 minutes. Under the ray of the sun, the degradation rate is almost 90%. The pH value could influence the degradation ratio. The pH greater than 7 is favorable to the degradation. The nanocomposition not only had high activities but also could be reclaimed and reused easily.
