- Abstract
In this study, we have synthesized MoS2 nanostructures (NSs) through a simple and facile hydrothermal method and studied various factors affecting the degradation of organic azo dye methyl red (MR) under the illumination of visible light. The as-synthesized photo-catalyst has been characterized by powder X-ray diffraction, Raman spectroscopy and transmission electron microscopy to confirm its structure and surface morphology. The results reveal that the prepared MoS2 NSs have 2H crystal phase. The peak frequency difference of ~25 cm−1 exhibits preparation of 5–6 layers of MoS2 NSs. Ultraviolet–visible spectroscopy has been utilized to study the change in percentage degradation of the dye with variation in dosages of photocatalyst, dye concentration and variation in pH of the dye. MoS2 NSs show the best adsorption of 80.35% at low pH of 4.24 with 14 mg of catalyst dosage and 50 ppm of dye concentration in 6 h of irradiation time.
