Preparation and Kinetic Property of Iron-Doped TiO₂ Nanoparticles

Abstract:

nanoTiO2 photocatalyst powders were prepared through the sol-gel method and with supercritical fluid drying (SCFD). The SEMXRD and particle size distribution technique were used to characterize the hyperfine TiO2 particles.The reaction of photo-catalysis for methylene blue is in conformity with the first order kinetic law in appearance within the concentration range between 5mg/L and 15 mg/L. As the initial concentration methylene blue in water increase, the appearance rate constant of the reaction decreases while the half-life period of the reaction increases.
