Trace-amount platinum doped sol-gel synthetized Ag-Al2O3 was investigated as HC-SCR catalysts. The doping resulted in an increase in the low-temperature NOx reduction activity and the improvement is most likely owing to an increased amount of partially oxidized hydrocarbon species on the catalyst surface.
