Abstract

The optimum conditions for the preparation of TiO2-Ag-Sm photocatalysts by microwave hydrothermal method are as follows: n(Ag+): n(Ti4+)=0.3%, microwave power 600 W, reaction temperature 150 ?"?, reaction time 3 h, calcination temperature 650 ?"? and calcination time 3h. The structure of the catalyst was characterized by XRD, SEM-EDS, ICP-AES, UV-Vis, IR and BET. The photocatalytic degradation activity of TiO2-Ag-Sm catalyst was investigated under the conditions of microwave, ultraviolet, microwave-ultraviolet and microwave-ultrasonic-ultraviolet under methyl orange solution as simulated pollutant. The results showed that methyl orange was almost degraded completely when the methyl-orange solution was degraded by microwave-ultrasonic-ultraviolet irradiation for 25 min.
