Photocatalytic degradation of triclosan in visible-light-induced via CdS@TiO2-rGO nanocomposite

With the ever-increasing impact of chemicals on our life, organic pollutants have emerged as a topic of significant concern. Photodegradation of organic wastes has exponentially jumped up as an advanced technology for pollutant termination from the system. There has been a range of photocatalysts that have been applied for the degradation of such organic compounds. Graphene-based ternary nanocomposites have shown a major pathway for combatting these organic pollutants. This article studied one such Ternary nanocomposite made up in situ; sonochemically synthesized and deposited CdS nanoparticles over Titania-reduced Graphene oxide (TiO2-rGO). The product obtained was washed with double distilled water and characterized by powder XRD, SEM, TEM and HRTEM, AFM, and solid-state UV-visible (DRS). It was further analyzed for its photoactivity through dye degradation on Methylene Blue compared with binary nanocomposites. Photocatalytic degradation of Triclosan was done using this ternary nanocomposite, and the rate constant was calculated to be around 2.7 x 10(-3) min(-1).
