Preparation and Kinetic Property of iron-doped TiO2 Nanoparticles

摘要：

　　Nano-TiO2 photocatalyst powders were prepared through the sol-gel method and with supercritical fluid drying(SCFD).The SEM、XRD 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.
