Facile Synthesis of an Advanced Visible-Light-Driven Organic-Inorganic Nanocomposite Photocatalyst for Efficient Removal of Hazardous Organic Pollutants and Bacteria from Water

Wide-ranging research have been conducted on the removal of hazardous organic pollutants and water-borne bacteria from water. Many methods of water purification, which involve complicated instrumentation and complex methodologies exist, which can also be a source of secondary contamination. Photo-catalysis is a simple and cost-effective method, in which the light-induced charge carriers generated in the semiconducting material are used to degrade and demineralize the organic, inorganic, and microbial pollutants in water through redox reactions. Synthesis of advanced organic-inorganic nanocomposite photocatalysts using nano-engineered semiconducting materials remains a method of choice for visible-light-induced degradation of hazardous organic pollutants and disinfection of water with bacteria owing to its effectiveness, simplicity, and low cost. In this project, funded by the Ministry of Education, the IRC-MWS team synthesized advanced organic-inorganic photo-catalytic materials using advanced pulsed laser ablation in liquid capable of operating under visible light, particularly using abundant solar radiation. This system was successfully used for photocatalytic degradation of hazardous organic pollutants and disinfection of water with bacteria. This material can be applied for decontamination and disinfection of water and in bio-films using solar light as the source of radiation, which is an application involving solar energy harvesting.
