Characterization of supported Pt catalysts and their activity in the reduction of N2O by H2
Introduction Fe-zeolites are widely used for catalytic N2O reduction in the presence of CO, CH4, NH3, C3H6, and C3H8, but reaction temperatures greater than 320℃ are required to obtain light-off performances, depending on catalysts and reductants. Recently, we have reported that the oxygen atoms adsorbed on Pt via dissociative N2O adsorption at 90℃ were completely titrated by H2 at 27℃, and that this H2-N2O titration reaction could be expanded to continuously reduce N2O at very low temperatures, such as 90℃ that is much lower, by 230℃, than that reported for the Fe-zeolites. This study has been focused on the reduction of N2O by H2 over supported Pt catalysts with different nanoparticle sizes.
