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。

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

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%.
