摘    要:采用柠檬酸修饰溶胶-凝胶法制备NiO-TiO2催化剂,然后于流化床反应器中直接在NiO-TiO2表面原位生长多壁碳纳米管,制备出CNTs-Ni-TiO2复合光催化剂。采用XRD、SEM、TG、BET、PL荧光光谱等方法对制备的样品进行了表征,以亚甲基蓝降解为模型反应,考察了复合催化剂在紫外线下的光催化性能。结果表明,在NiO含量为5%的NiO-TiO2催化剂上生长CNTs后得到的CNTs-Ni-TiO2复合材料具有较高的光催化活性。

关 键 词:溶胶-凝胶法  流化床  CNTs  光催化  TiO2  化学气相沉积

Abstract:NiO-TiO2 catalyst was prepared with the modified citric acid sol-gel method.Carbon nanotubes(CNTs)was directly grown on the surface of the NiO-TiO2 by fluidized bed chemical vapor deposition(CVD).The prepared CNTs-Ni-TiO2 nanocomposite photocatalysts were characterized by XRD,SEM,TG,BET and PL.The photocatalytic performance of CNTs-Ni-TiO2 was evaluated by degradation of methylene blue under UV light.The results indicated that CNTs-Ni-TiO2 nanocomposite showed the highest degradation activity when the dosage of NiO was 5%.
Keywords:sol-gel  fluidized bed  CNTs  photocatalysis  TiO2  chemical vapor deposition
