Catalyst Systems

The catalysts based on V/K/Ca and V/Ks/Ce systems for diesel soot catalytic oxidation were synthesized onto the porous alumina substrates. Both catalyst systems showed a good catalytic oxidation activity. The V/K/Ca system exhibited the lowest oxidation onset temperature (OOT) of about 359oC with a composition of V/K/Ca =1:1:0.1 where the V and Ca and/or K elements could form a kind of amorphous phase that determined the catalytic activity. The V/Ks/Ce system displayed the lowest OOT of about 350oC with a composition of V/Ks/Ce = 1:2:0.1 where the K2SO4 and K5V2O3(SO4)4 phases could contribute most to the catalytic activity.

Gold nanoparticles supported on transition metal oxide catalysts have been prepared by deposition-precipitation. Their catalytic activity with or without Au doped has been tested for soot oxidation. Au improves the catalytic activity of transition metal oxide for the oxidation of soot particles. Under the catalysis of Au/Co3O4, the initial oxidation temperature of soot is 354 ℃.
