Promotional effect of Sn on NO oxidation over Pt/Al2O3 as promising gas exhaust catalytic converter. Selective Pt and Sn dispersion determination
NO oxidation was investigated over Pt-Sn/gamma-Al2O3. The addition of Sn to 1%Pt/gamma-Al2O3 enhances NO oxidation to NO2. This effect is related to the enhancement of chemisorbed oxygen on the metallic surface produced by Sn.
