以沸石为载体，以钛酸丁酯和尿素为助剂，采用溶胶‐凝胶法制备沸石负载 N ／TiO2光降解催化剂．在可见光下对罗丹明 B 进行降解实验，讨论影响罗丹明 B 降解性能的主要因素．结果表明，当微波反应15 min ，焙烧温度为450℃、催化剂用量为40 mg／L 、光照时间为30 min 时，样品对罗丹明 B 的降解率可达99．2％以上．光降解催化剂再生后重复使用4次，降解率仍可达89．7％．

The nitrogen‐doped TiO2 photocatalysts were prepared by sol‐gel method ,using trtrabutyl titan‐ate and carbamide as raw materials and zeolite as the supporter .The major factors were tested and discussed to photocatalyst degradation of rhodamine B in the sunlight .The results showed that after the microwave reaction was conducted for 15 min ,the rhodamine B degradation rate of 30 min may reach above 99 .2% in visible light when the dosage of 40 mg/L and the roasting temperature was 450 ℃ .The degradation rate could reach 89 .7%after the photocatalyst was regenerated for 4 times.
