| 摘 要： | 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15min,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%.

| Abstract: | The nitrogen-doped TiO2 photocatalysts were prepared by sol-gel method,using trtrabutyl titanate 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 40mg/L and the roasting temperature was 450℃.The degradation rate could reach 89.7%after the photocatalyst was regenerated for 4times |
