We report synthesis of light-induced heterogeneous photocatalyst PbSnO3 by green chemistry approach, using mechanochemical method. The synthesized catalyst was characterized physically by various analytical investigative techniques like UV-DRS, FTIR, XRD, SEM, EDAX, TEM, and TG. The product corresponded to average particle size of 100 nm by TEM images. Photocatalytic activity of PbSnO3 was studied by photodegradation of Methyl blue, Indigo carmine, and Acid violet dyes under sunlight. The results indicate that the sunlight stimulates a photochemical reaction and successfully complete mineralization of Methyl blue, Indigo carmine, and Acid violet dyes. Antimicrobial activity shows that PbSnO3 photocatalyst was found non-toxic to the environment.
