MoS2 and CdS photocatalysts for water decontamination: A review

Abstract
Abstract\r\nSemiconductor photocatalytic technology, driven by solar energy, represents an attractive strategy to relieve or perhaps even resolve many environmental pollution issues. The semiconductor-based photocatalysts, MoS2 and CdS, have attracted considerable attention for water decontamination owing to their unique properties of tuneable bandgap, high absorption of visible light, and excellent electronic-charge transfer capability. In this review, the following topics are presented: the mechanism of semiconductor photocatalysis, the synthetic strategies employed in preparing MoS2 and CdS nanostructured photocatalysts, and their applications in wastewater treatment. In addition, possible approaches to improve their photocatalytic performance, such as modification of morphology, shape, and crystallinity are discussed together with heteroatom doping, and metal sulfide, metal oxide, and carbon compound nanocomposite formation.
