摘要：

The catalytic performance of Nb doped Ag/Al2O3 was investigated for the selective catalytic reduction of NOx (SCR) in diesel engine exhaust using light gas oil as a reducing agent. The catalytic activity of Ag/Al2O3 slightly increased by addition of Nb. The adsorbed amount of sulfur of Ag-Nb/Al2O3 was lower than that of Ag/Al2O3. Then the degree of deactivation of Ag-Nb/Al2O3 was smaller than that of Ag/Al2O3.
