Preparation and Photocatalytic Activity of Ag-TiO₂/CNT Photocatalyst

Abstract:

Ag doped TiO2 was formed on the surface of carbon nanotube(CNT) by the sol-gel method, and characterized by TEM, XRD. The photocatalytic activity of the Ag-TiO2 /CNT was evaluated in degradation of methyl orange with a 300 W high pressure mercury lamp. Effect of Ag doping quantity on the photocatalytic activity of the photocatalys was investigated.The photocatalytic experiment indicated that the photocatalytic activity was firstly improved and then decreased with an increase of amount of Ag doped in TiO2 nanoparticles,the optimal doping quantity was 0.8% silver （ mass fraction of TiO2）, methyl orange could be degraded 99.3 % by Ag-TiO2/CNT under the optimal conditions after 120min.
