Abstract

Molybdenum Disulphide (MoS2) based materials in pure form or composites are known for their photocatalytic activity including wastewater treatment and purification. In the present study, pristine MoS2 nanosheets and MoS2@TiO2 composite nanosheets are synthesized via grinding-assisted sonication process with N-Methylpyrrolidone (NMP) as solvent. TiO2 being environment friendly with high photochemical stability, provides a suitable reinforcement material for photocatalytic applications. The prepared dispersions are characterized by UV-Vis, Raman and FTIR spectroscopy for structural and optical properties. These nanosheets are tested for methylene blue dye degradation in dark and in the presence of sunlight at intervals of 30 minutes. The MoS2@TiO2 nanosheets show enhanced degradation efficiency in comparison to the pristine MoS2 nanosheets. These composite nanosheets are potential materials in tackling dye pollutants for application in wastewater treatment plants and purification.
