Abstract:
Our present paper aims to design environment friendly, highly effective, reusable and low cast photocatalysts to destroy harmful pollutants like phenolic compounds and various types of dyes such as methyl green which are liberated from many industries and produce water pollution at large scale along with biological pollutants like fungi and bacteria. Graphene oxide based some stable nanocomposites with metal sulphides will be prepared by simple coprecipitation method using DMF as a solvent as well as a reducing agent for metal sulphide nanoparticles. Sodium sulphide will be employed as sulphur source in zinc sulphide nanoparticles. In the next step, doping of zinc sulphide will be carried out with different weight % of cost-effective noble metal i.e., silver by in-situ synthesis of silver nanoparticles. Prepared nanomaterials are characterized in detail to study their composition, morphology and stability. Photocatalytic properties are investigated by employing the prepared materials as photocatalysts for the reduction of some phenolic compounds like resorcinol and 3-chlorophenol. Photocatalytic reactions were monitored by UV-Visible spectroscopic technique. Effects of various parameters like pH of medium, concentration effect and loading of silver nanoparticles with different ratio was also studied to tune the photocatalytic response under UV light source. Additionally prepared materials were also utilized to study adsorption of different dyes from waste water along with anti-bacterial applications against various bacterial strains.
