Photocatalytic performance of CoS2-graphene-TiO2 ternary composites for reactive black B (RBB) degradation

Abstract

In this study we examined the photo-degradation efficiency of CoS2-G-TiO2 nanocomposites under visible light irritation using Reactive Black B (RBB) as standard dye, CoS2-G-TiO2 nanocomposites synthesized by facial microwave assist technique, and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopic analysis. Our results show the efficiency of the CoS2-G-TiO2 ternary nanocomposite is better than CoS2-G and TiO2-G nanocomposite. The degradation efficiency of CoS2-G-TiO2 nanocomposite was found approximately 89% of Reactive Black B (RBB) degraded after 180 min. Our results will open new way for the development of a new ternary nanocomposite photocatalytic application.
