摘 要: | SO2-4/TiO2固体酸可用于光催化降解溴代甲烷,其光催化性能明显优于TiO2光催化剂.在相同反应条件下,SO2-4/TiO2的光催化活性比TiO2提高2~10倍.当H2SO4浸渍液浓度为1mol/L时,制得的SO2-4/TiO2酸性最强(H0<-12.14),具有超强酸性和最高的光催化活性.

Acid Strength and Photocatalytic Activity of SO2-4/TiO2 Solid Acid Catalyst |
| |
Abstract: | SO2-4/TiO2 solid acid was used for photocatalytic degradation ofCH3Br, and its photocatal ytic activity is 2~10 times higher than that of TiO2 under the same reaction conditions. The SO2-4/TiO2 sample impregnated w ith H2SO4 solution (1 mol/L) is of superacidity (H0<-12.14), possessing the highest acid strength and the highest photocatalytic activity for degradation of CH3Br. |
