| heal.abstract | The present work deals with the comparative application of the CPSM (corrugated pore structure model), the a. plot and the pore connectivity methods for pore structure analysis and especially the detection of microporosity of a category of montmorillonite clays pillared with LaNiO(x). binary oxide. A quite good agreement between the corresponding results deduced from the three methods was confirmed. The raising of the LaNiO(x) content caused a change of pore volume, surface area, and microporosity whereas the relevant curves pass through a maximum. The CPSM model, through the simulation of gas sorption hysteresis, enables the evaluation of unified mesomicropore size distributions, pore surface areas, tortuosity factors, tau(CPSM), and relative microporosities. It is also concluded that pore tortuosity, (tau(CPSM)), is inversely proportional to the pore connectivity factor (c), and the nominal pore length (N(s)) (i.e., a CPSM parameter) is proportional to the number of pore lengths (L) (i.e., a parameter of the pore connectivity model). | en |
