| 摘 要： | 分别用花粉和柠檬酸为模板剂制得了光催化剂TiO2（HF）和TiO2（NM）,并在紫外光下进行龙胆紫、蕃红花T、罗丹明B水溶液染料的降解实验。通过2 h的降解,用柠檬酸为模板剂制得的TiO2对蕃红花T染料的降解率达到77%,对罗丹明B染料的降解率达到了88%,对龙胆紫的降解率达到了90%,而用花粉为模板剂制得的TiO2对蕃红花T染料的降解率达到67%,对罗丹明B染料的降解率达到了37%,对龙胆紫的降解率达到了56%。结果显示,用柠檬酸为模板剂制得的TiO2的降解效果比用花粉为模板剂制得的TiO2明显得多,即前者的催化效率高于后者。 |

| Abstract: | TiO2 was successfully synthesized by pollen and citric acid as template and used for the photodegradation of rhodamine B,safranine T and gentian violet under UV light.It was found that the synthsised TiO2 using citric acid ex-hibited high photoactivity and the photodegradation yields were 88%,77%,90%for rhodamine B,safranine T,and gentian vio-let,respectively.Moreover,TiO2 was successfully synthesized using pollen as template and used for the photodegradation of rhodamine B,safranine T and gentian violet under UV light,and the photodegradation yields were 37%,67%,56% for rhodamine B,safranineT,and gentian violet respectively. |
