摘要：
Selective catalytic reduction of NO (x) by H-2 in the presence of oxygen has been investigated over Pt/ Al2O3 catalysts pre-treated under different conditions. Catalyst preparation conditions exert significant influence on the catalytic performance, and the catalyst pre-treated by H-2 or H-2 then followed by O-2 is much more active than that pre-treated by air. The higher surface area and the presence of metallic Pt over Pt/Al2O3 pre-treated by H-2 or pretreated by H-2 then followed by O-2 can contribute to the formation of NO2, which then promotes the reaction to proceed at low temperatures.
