Photocatalytic Degradation of Eriochrome Black-T Using BaWO4/MoS2 Composite

Abstract

Photocatalytic degradation of organic compounds using semiconductor oxide materials has attracted increased attention in the recent decades. Both the catalysts and light play an important role in the photocatalytic degradation process. This research work focuses on the synthesis of BaWO4/MoS2 composite using green chemical method and its use in the degradation of Eriochrome black-T dye. Synthesized BaWO4, and BaWO4/MoS2 composites were characterized by XRD, XPS, Raman, SEM, TEM, BET and UV-Vis characterizations techniques. BaWO4/MoS2 composite exhibits superior photocatalytic performance towards Eriochrome black-T degradation than BaWO4. Superior photocatalytic activity of BaWO4/MoS2 composite corresponds to enhanced light absorption, effective charge generation, separation, and minimum recombination of photogenerated charge carriers.
