STUDY OF PHOTOCATALYTIC ASSET OF LEAD TITANATE SYNTHESIZED BY ECO-FRIENDLY MECHANOCHEMICAL METHOD

Lead titanate particles in the nanometer size regime have been successfully synthesized by mechano-chemical method using green chemistry approach. The structural and micro structural properties of PbTiO3 material was characterized by various investigative techniques like FT-IR, UV-DRS, XRD, SEM, TGA and Electrical Conductivity. The particle size of PbTiO3 was found to be 64 nm by XRD. Electrical properties show semiconducting nature of synthesized lead titanate. The thick films of the material were prepared by screen printing method. The synthesized material was used for photo degradation of methylene blue dye with respect to various dye concentrations and catalyst amount under sunlight. Degradation product analysis was done using the LC–MS technique (Liquid chromatography–mass spectrometry ) and the results shows that the dye degradation. The degraded product tested for the phytotoxicity and show good results. Degradation products were less toxic and more similar to pure water compared to methylene blue. PbTiO3 photo catalysts was found to be nontoxic to the environment.
