摘要

摘要: 采用溶胶-凝胶法制备一系列不同Cu/V比例的Cu-V-O催化剂，利用XRD、BET、H₂-TPR等手段对催化剂进行了表征，并考察其催化燃烧甲苯的活性和抗硫性。结果表明，适量的Cu掺杂会提高催化剂比表面积，而且Cu-V可以形成Cu₃V₂O₈晶型结构，使V₂O₅晶格氧活动增加，提高催化剂氧化-还原能力。其中，Cu_0.15V_0.85催化剂表现出最佳的活性和抗硫性；通过TiO₂负载可以进一步提高催化剂对甲苯的催化燃烧活性和抗硫性。

Abstract: A series of Cu-V-O oxide catalysts with different Cu-V molar ratios were prepared by the sol-gel method. The catalysts were characterized by means of XRD, BET and H₂-TPR. The catalytic activity and sulfur resistance for toluene combustion were tested. The results indicated that Cu₃V₂O₈ crystal structure was formed in the catalyst, which improved the lattice oxygen in the structure of Cu-doped catalysts and increased the surface area, leading to better re-dox-ability of the catalysts. The Cu_0.15V_0.85 catalyst showed the best activity and sulfur resistance. The loading of TiO₂ can significantly improve the catalytic combustion activity and sulfur resistance of the mixed oxide catalysts.
