摘　　要：以溶胶 -凝胶法制得锐钛矿型结构的 Ti O2 /glass膜。在紫外灯照射下研究了膜对水中苯酚的光催化降解作用 ,研究证明 ,灯距控温反应器 1 0 cm时的液外照射 ,可使苯酚降解率达 70 %以上 ;在 H2 O2 存在下效果更佳 ;Anatase TiO 2/glass films have been prepared by a sol gel method. The photocatalytic degradation of phenol in water on the films under UV irradiation was investigated. When the lamp was 10 cm away from the reactor, the degradation rate of phenol was over 70%. The degradation rate was improved in the presence of H 2O 2, and the degradation could be almost complete in air flow.
