Evenly supported TiO2 on activated carbon fiber and its photocatalytic degradation property

Activated carbon fiber (ACF) supported TiO2 photocatalyst was prepared by sol-gel-adsorption method. The state of TiO2 supported on the ACF was observed using a scanning electron microscope. Photo catalytic activity of the catalyst was evaluated by degradation of methylene blue in water, and the ways in which the efficiency of methylene blue degradation was influenced by TiO2 load content and pH value were investigated. The supported catalyst shows cooperative effect of ACF adsorption and TiO2 catalytic activity, and the catalytic activity of the supported catalyst was basically unchanged after using for four times.
