Degradation of Methyl Orange Under Visible Light by ZnO-Polyaniline Nanocomposites

The ZnO-Polyaniline nanocomposites with ratios of 9:1, 8:2, and 7:2 were successfully synthesized using a grinding method in ethyl alcohol. The XRD, TEM, and SEM characterizations are used for the analysis of the nanocomposites. The entire three nanocomposites were degraded by methyl orange in the presence of visible light. We get the best results for ZnO-Polyaniline (7:3) catalyst. About 82 % degradation of methyl orange was observed below visible light within 140 minutes.
