PHOTOCATALYTIC DEGRADATION OF ALIZARIN RED AND XYELENE ORANGE DYES USING Au- ZnO-In2O3-Pt NANOCOMPOSITE

Abstract

The present study focuses on the biosynthesis of nanocomposite (Au-ZnO-In2O3-Pt) along with its photocatalytic
activity. The Au-ZnO-In2O3-Pt nanocomposite was synthesized using Cocos nucifera flower extract and was characterized
using UV-vis spectroscopy and SEM. The photocatalytic activity of the nanocomposite has been tested on the degradation
of organic dyes such alizarin red and xylene orange in aqueous solution under direct sunlight. The effect of various
parameters such as pH of solution and total organic content (TOC) is studied thoroughly during degradation reactions.
