Abstract

The intensity of the white line of the LII and LIII x-ray absorption edge spectra of small platinum particles increases with decreasing particle size. The combined white line intensity of the LII and LIII x-ray absorption spectra for platinum catalysts with comparable av. particle size is higher when dispersed on acidic than on neutral supports. This indicates that Pt particles are more electron deficient on acidic than on neutral supports. The propane hydrogenolysis TOF for Pt supported on g-Al2O3 or H-LTL is more than an order of magnitude higher than for Pt supported on a nonacidic K-LTL zeolite. The differences in catalytic behavior are related to differences in the d-band d. of states. [on SciFinder (R)]
