- The effect of aging atmosphere (Ar, H2, O2, SO2, SO2+O2) during thermal aging of Pt/Al2O3 model diesel oxidation catalysts was studied. More specifically, the impact of the aging on the NO oxidation activity and platinum dispersion was investigated. Thermal aging caused a decrease in dispersion and an increase in NO oxidation performance. However, the aging behavior was strongly correlated with the nature of the ageing atmosphere. Catalysts with similar dispersion could have very different NO oxidation activity, depending on which atmosphere that they were aged with.
