Comparative study of photocatalytic activity of hydrothermally synthesized ultra-thin MoS2 nanosheets with bulk MoS2

The emergence of 2D materials has gained immense attention for photocatalytic applications due to their thickness dependent physical and chemical properties. In this paper, MoS2 nanosheets were synthesized by low cost hydrothermal method. The sample was well characterized by X-ray diffraction (XRD) and UV-Vis spectroscopy and scanning electron microscopy (SEM) micrographs confirm the formation of MoS2 ultra-thin nanosheets. A deep and extensive photocatalytic comparative study is performed on bulk MoS2 with hydrothermally synthesized MoS2 nanosheets under the sunlight by the degradation of methylene blue (MB) dye.
