TiO_2光催化剂载体的选型及负载方法研究

Selection on Carriers of Immobilized Photocatalyst TiO_2 and Study Methods of Immobilization

选择Al2 O3空心颗粒、石英管和玻璃珠等为载体制备了几种负载型TiO2 光催化剂 ,并通过十二烷基苯磺酸钠 (简称DBS)的光降解反应研究了催化剂负载方法及其对催化剂活性的影响 ,确定了制备负载型TiO2 光催化剂的最佳负载方法。

Several different kinds of immobilized photocatalysts are prepared by using Al 2O 3 particles,quartz and glass particles as carriers.The influence of the immobilization,running times and different preparing ways of the photocatalyst by its degradation of DBS are studied.In the end, the immobilized photocatalyst with good preparation and performance is determined.
