Structural and Optical Study of Tio2 Photocatalyst Doped with Thiourea

Authors(3) :-G. D. Gena, T. H. Freeda, K. Monikanda Prabu

The undoped and thoiurea doped TiO2 nanoparticles were prepared via Sol-Gel method by hydrolysis of titanium (IV) isopropoxide with thiourea. The catalyst powder was characterized by powder X-ray diffraction (PXRD), FT-IR and UV-Vis absorption and PL spectral studies. Powder X-ray diffraction analysis show that the structure of the prepared samples are anatase polycrystalline structure. FTIR spectrums for undoped and thiourea doped samples show a broad band between 500 and 800 cm−1. The optical study shows that thiourea doping leads to increase in the absorption edge wavelength, and a decrease in the band gap energy of TiO2 nanoparticles.
