| We prepared Pt catalysts supported on various zeolites, viz. H-Y, Na-Y, H-ferrierite, and H-β, and applied them to propane combustion. Pt/H-Y showed a higher catalytic activity than Pt/Na-Y although both catalysts exhibited a similar Pt dispersion. In the case of Pt/H-β and Pt/H-ferrierite, the catalytic activity increased but the Pt dispersion decreased with increasing SiO2/Al2O3 molar ratios of H-zeolites. |
