摘要：

Ga2O3/Al2O3 prepared by sol-gel method showed excellent activity for the selective reduction of NO with propene in the presence of H2O, compared with Al2O3, Ga2O3 and impregnated Ga2O3/Al2O3. Its high activity was hardly influenced by the presence of SO2. It was suggested from the results of XPS studies that the presence of gallium oxide interacting strongly with alumina is responsible for the catalytic performance of Ga2O3/Al2O3.
