Preparation of Loaded Nanosize TiO2-Photocatalyst in Reverse Micelle System

Abstract

Abstract: TiO₂ nanoparticles with a diameter of 2-5 nm were prepared by reverse micelle method and characterized by TEM, DSCand XRD. The loaded nanosize TiO₂ photocatalyst supported by small porous molecular sieve HZSM-5 was obtained by impregnating method and identified by FTIR, Langmuir, BETand BJHadsorption. The synthesized pure TiO₂ nanoparticles and loaded nanosize TiO₂ were respectively used as photocatalyst to degrade K₂Cr₂O₇ in aerated solution. The UV-Vis spectra indicated that the photocatalytic activity of the loaded TiO₂ nanoparticles was higher than that of the pure.
