摘　　要：采用混胶法将铝溶胶与钛溶胶相混合制备出纳米级γ-Al_(2)O_(3)/TiO_(2)复合载体,然后用共浸渍法制备出不同钒含量的V/γ-Al_(2)O_(3)-TiO_(2)催化剂,并对其活性进行评价,结果发现5%V2 O5/γ-Al_(2)O_(3)-TiO_(2)催化剂对乙醇和乙醛等具有良好的催化氧化性能.通过XRD等技术对催化剂进行了表征,合理解释了V/γ-Al_(2)O_(3)-TiO_(2)催化剂有较高活性的原因.Nanoscaleγ-Al_(2)O_(3)/TiO_(2)composite carriers were prepared by mixed aluminum sol and titanium sol,and then V/γ-Al_(2)O_(3)-TiO_(2)catalysts with different vanadium contents were prepared by impregnation.The results show that ethanol and acetaldehy were completely oxidized on 5%V2O5/γ-Al_(2)O_(3)-TiO_(2)catalyst.Its high oxidation activity were reasonable explaining by XRD techniques.
