Preparation of TiO(2)/Black Talc Composite Photocatalyst and the Research on Its Adsorption-Degradation Coupling Effects
In this paper, a TiO(2)/black talc composite photocatalyst was prepared by the sol-gel method using TBOT as titanium source and black talc as carrier. Rhodamine B was used as the targeted pollutant to study the adsorption role of carbon in black talc. The results showed that with the adsorption-degr...

Sumario: | In this paper, a TiO(2)/black talc composite photocatalyst was prepared by the sol-gel method using TBOT as titanium source and black talc as carrier. Rhodamine B was used as the targeted pollutant to study the adsorption role of carbon in black talc. The results showed that with the adsorption-degradation cycles, the illumination time can be reduced by 40%. The adsorption rate and degradation rate of the composite photocatalyst was also increased. The degradation rate of Rhodamine B reached more than 95%, which fully shows the synergistic effect between TiO(2) nanoparticles and black talc. In this way, the adsorption-degradation coupling of the photocatalyst could be realized. |
