摘　　要：本文以5A分子筛为载体、以钛酸正丁酯为原料,采用溶胶—凝胶法制备了负载型TiO_2/5A分子筛复合光催化剂,并通过XRD对样品进行了表征。实验中以300W高压汞灯为光源,研究了TiO_2/5A分子筛复合光催化剂对亚甲基蓝溶液光催化氧化的效果。结果表明：采用TiO_2/5A分子筛作为光催化剂对10mg/L的亚甲基兰溶液光催化30分钟后,光催化脱色率可达86．97%,脱色效果较为明显。TiO2/5A zeolite composite has been prepared by a sol-gel method with titanium tetrabutoxide as its precursor and 5A zeolite as its the carrier .The photocatalysts are characterized by XRD. Irradiations are performed with a 300 W high pressure mercury lamp. The result of photocatalytic degradation of methylene blue indicates that TiO2/5A zeolite composite has high photeoatalytic activities. After 30minute reaction, the decolanring efficiency of 10 mg/ L methylene blue solution reaches 86.9% with 1.2 g/L of the photocatalysts.
