Methylene Blue Degradation

Activated carbon fiber (ACF) supported TiO2photocatalyst was prepared by sol-gel-adsorption method. The state of TiO2supported 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 TiO2load content and pH value were investigated. The supported catalyst shows cooperative effect of ACF adsorption and TiO2catalytic activity, and the catalytic activity of the supported catalyst was basically unchanged after using for four times.

The Ba doped tantalum oxide (Ba-Ta2O5) particles were synthesized using low temperature hydrothermal method. The phase structure of samples was characterized by X-ray diffraction (XRD). The result showed that Ba-Ta2O5 had still good crystallinity and belonged to rhombic crystal. The catalytic activity of samples was investigated with the degradation methylene blue (MB) under visible light. The degradation efficiency attained 82% when the reaction time was 12 h. The kinetics of MB degradation was respect to the first-order.
