Visible light-driven photocatalytic degradation of organic pollutants by nanocompositebased on layered double hydroxides

With the increasing development of industries, water pollution by organic pollutants such as dyes hasbecome a serious environmental crisis. The purpose of this research is to design and synthesize a nanocompositebased on LDH to enhance the separation of charge carriers and improve the photocatalytic performance for thedecomposition of the MB dye under visible light irradiation. Nanocomposite prepared via hydrothermal and coprecipitationmethods. Various analyses including FT-IR, FE-SEM, TEM, XRD, EDX, UV-Vis DRS, DLS, ZetaPotential, PL, CV, EIS, TPC, and LSV were conducted to characterize and study the synthesized samples. Theeffect of adsorption, amount, and pH on the photocatalytic efficiency was investigated. Active agents wereidentified by scavengers, and a photocatalytic degradation mechanism was proposed.
