ABSTRACT

Pore-widths and pore-size distributions of 0.5 wt% Pt-CsxH3-xPW12O40 have been studied by means of adsorption of various molecules. For the distributions of micropore and mesopore, isotherms of Ar and N2 adsorption were analyzed, respectively. Pt-Cs2.1H0.9PW12O40 possessed only ultramicropores. On the other hand, the pores of Pt-CsxH3-xPW12O40 (x = 2.3, 2.5, 2.8 and 3.0) showed bimodal distributions in the range from micropore to mesopore, and the widths of both pores tended to increase as the Cs content increased. From the amounts and rates of adsorption for n-butane and isobutane, the pore width of Pt-Cs2.1H0.9PW12O40 was determined to be close to the molecular size of n-butane, that is, 0.43 nm. The fraction of external surface area in the total surface area of Pt-Cs2.1H0.9PW12O40 was estimated to be only 0.06 from the adsorption of 1,3,5-trimethylbenzene and t-plot of N2 adsorption. Pt- Cs2.1H0.9PW12O40 exhibited a shape selectivity due to the uniform ultramicropores and small external surface area; it catalyzed the oxidation of n-butane but not that of isobutane. SEM and TEM measurements revealed the primary crystallites and their aggregated states. More... »
