Argon porosimetry of selected molecular sieves: experiments and examination of the adapted Horvath-Kawazoe model

Characterization of micro- and mesoporous solids by physisorption methods and pore-size analysis

“…As shown before by Saito and Foley [17], both transitions are present and indicate volume uptake in different p/p 0 regions (Fig. 10).…”

“…The argon data used in conjunction with the Horvath±Kawazoe (HK) model provides realistic pore-diameter values. The same plot has been used by Saito and Foley [17] and Hathaway and Davis [18]. Borghard et al presented their results of argon sorption experiments with ZSM-5 by plotting the ®rst derivative of the adsorption isotherm vs. the log of the relative pressure [19].…”

One-pot catalyst preparation: combined detemplating and Fe ion-exchange of BEA through Fenton's chemistry

“…Microporosity formation was confirmed by high resolution low-pressure Ar physisorption. § The pore-size distribution, calculated according to the Saito-Foley model 6 applied to the adsorption branch of the isotherm, confirms the presence of microporosity in the one-pot catalyst. A pronounced development of a pore-size distribution between 5 and 8 Å with a maximum at 6 Å , characteristic of BEA channels (,100.…”

Polymer-Derived SiBCN Ceramic and their Potential Application for High Temperature Membranes Dedicated to Prof. Dr.-Ing. Dr.h.c. Hartmut Fuess on the occasion of his 65th birthday

“…The micropores r pore ࢻ2.0 nm and mesopores 2.0 nmࢻr pore ࢻ50 nm of the amorphous SiBCN thin film were characterized by the SF 26,27 and BJH 28 method, respectively.…”
