The activity of the catalysts . varies with oxidising agent and the presence of surface SO42-.. NO(g) increases conversion of soot to COx-. Surface SO42- has no effect on activity for the C-(s) + O-2 reaction but decreases activity in the Carbon + NO/O-2 oxidation. This is interpreted in terms of SO42- blocking NO adsorption sites, thus poisoning the 4 NO + O-2 --> NO2 reaction, which is essential for the NOx promoted oxidation.||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Catalysis Communications||Volume:||6||Issue:||7||Start page:||472||End page:||475||Copyright (published version):||2005 Elsevier B.V.||Keywords:||Soot combustion; Sulphate; NOx||DOI:||10.1016/j.catcom.2005.04.008||Language:||en||Status of Item:||Peer reviewed|
