17-P-13 - Pore size analysis with H2O adsorption measurement of organically modified MCM-41 type materials

摘要: Publisher Summary This chapter discusses pore size analysis with the H2O adsorption measurement of organically modified MCM-41 type materials. Hexagonally structured mesoporous molecular sieves (MCM-41) containing organic groups have been synthesized under various conditions and are used to test applicability Kelvin equation water adsorption. The estimation, assuming corrected for statistical film thickness H2O, is in good agreement that obtained N2 relatively hydrophilic samples when appropriate value radius curvature meniscus used. correction contact angle necessary hydrophobic materials match sizes estimated on basis those by
