摘要
Mesoporous TiO2 frameworks were synthesized by the sol-gel combined with evaporation-induced self-assembly (EISA) methods using F127 as the templating agent. Based on the obtained mesoporous TiO2, Ag/AgCl/mosoporous TiO2 composites were synthesized by the method of depositing AgCl and then reducing partial Ag+ ions to Ag-0 under mercury lamp irradiation. SEM. XRD were used to characterize the composites, and the efficiency of photodegradating methyl orange (MO) is also investigated. The results reveal the prepared TiO2 frameworks are composed of well crystallized anatase, and AgCl can be identified as chlorargyrite. The incorporation of Ag and AgCl has not destroyed the mesoporous TiO2 frameworks. Compared with pure mesoporous TiO2, the photodegradation efficiency of the composites is almost doubled. The increase of photodegradation efficiency is attributed to surface plasmon resonance absorption of Ag.
