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.
