Pore-Volume and Surface Area in Microporous-Mesoporous Solids
Original language description
To show the correct evaluation of pore-volume and surface area in microporous-mesoporous samples a series of mechanical mixtures of microporous zeolite NaY, and mesoporous gama-alumina was prepared. The nitrogen adsorption isotherms (77 K) were analyzedby the modified (three parameters) BET equation and compared with the independent textural information obtained a) from t-plots (with the standard isotherm of nonporous alfa-alumina and the standard isotherms of Lecloux-Pirard) and b) by subtracting theisotherm of the parent NaY from mixed sample isotherms. For illustration, the failure of classic (two-parameter) BET equation for samples of this type was demonstrated.
