One Pot Synthesized 2H - MoS2 as Efficient Photocatalyst for Degradation of Titan Yellow Dye under Solar Light Illumination

Molybdenum disulfide (MoS2) was synthesized and employed as a promising catalyst under sunlight illumination for the photocatalytic degradation of Titan yellow (TY) dye. The structural and physiochemical features of the hydrothermally synthesized MoS2 nanoparticles were examined by X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Field Emission Scanning Electron Microscopy (FESEM), High-Resolution Transmission Electron Microscopy (HR-TEM) and UV-Vis spectrophotometer. XRD affirmed the formation of 2H-MoS2, which is the most stable phase of the MoS2. Additionally, morphological insights into the MoS2 nanospheres were obtained through Field Emission Scanning Electron Microscopy (FESEM). The photodegradation process and energy band gap value were analyzed using UV-visible absorption spectroscopy. Due to visible light responsive band gap of synthesized MoS2, it showed excellent degradation efficiency of 96 % under natural sunlight in a small-time duration (12 minutes). All the characteristics features of this study anticipated that MoS2 can be used as potential photocatalyst for cleaning our river, water treatment and environmental remediation.
