Enhanced Photocatalytic Activity of the Cu2SnS3 + GO Composite for the Degradation of Navy Blue ME2RL Industrial Dye

Abstract

In the present work, the photocatalytic activity of pristine Cu2SnS3 (CTS) and a composite with graphene oxide (GO), i.e., CTS + GO, prepared by the precipitation technique, and its utilization as a catalyst for the degradation of Navy Blue (NB) ME2RL reactive azo dye were studied. The structural, morphological, and optical properties of the synthesized composite were evaluated. The degradation of azo dyes was used to evaluate the photocatalytic activity of the CTS + GO composite under visible light irradiation. When compared to pure CTS, the CTS + GO nanocomposite demonstrated increased photocatalytic activity. The improved photocatalysis is due to reduced recombination of generated charge carriers, better visible light absorption, and modified dye absorption via GO amalgamation in CTS. The simple and well-organized chemical bath method for catalyst preparation will be more suited to industrial production.
