摘要
Mesoporous TiO2 microspheres were prepared by a hydrothermal reaction and are characterized in this paper. Decoloration and mineralization during photodegradation of Orange II by mesoporous TiO2 at different pH values, formation of sulfate, relative luminosity to luminous bacteria and recycling experiments of the catalyst were studied. The FTIR results further suggested that the novel mesoporous TiO2 can not only decolor and mineralize dyes completely but also can be effectively reused several times. On the basis of the research, mesoporous TiO2 would be a promising photocatalyst for practical use.
