Ternary Nanocomposite for Solar Light Photocatalyic Degradation of Methyl Orange

In the present work, we reported the preparation of ZnO/PANI/RGO ternary nanocomposite by physical blending method and its photocatalytic efficiency of degradation of methyl orange under solar light. The samples were characterized by XRD, FTIR and UV–Vis spectroscopy. Optical band gap was calculated using Tauc plot for ZnO, PANI and RGO. The photocatalytic studies were evaluated using Methyl Orange with a degradation rate of 99% in 50 min. It is observed that photocatalytic efficiency enhanced by PANI (wt%). The PANI has the ability to create more charge carriers and delay the recombination process. The kinetic studies fitted to pseudo first order reaction. The nanocomposite acts as a promising photocatalyst for the removal of organic pollutants from water.
