“…[14], the MCM-48 powder and membrane were prepared as follows: Sodium hydroxide and cetyltrimethylammonium bromide (CTAB) were dissolved in deionized water, which was heated to 40°C. The tetraethyl orthosilicate (TEOS) was added after the mixture was stirred for 30 min.…”

“…Kim et al [11], using a thermal decomposition treatment during calcination, removed the filler PVA after the silica thin film. In the process of high-temperature calcination, it not only affected the lattice structure of MCM-48 molecular sieve [8,9,14], but also caused membrane surface cracking due to the different coefficients of thermal expansion between support and film layer.…”

“…In previous work [14], we had synthesized MCM-48 membranes on zirconia support with an average pore size of 0.2 μm by solvent extraction with the surfactant template. In this study, we reported that the asymmetric zirconia tubular support was pretreated with water as a pore-filling substance, and controlled the same pH value of aqueous solution with MCM-48 sol.…”

Mesoporous MCM-48 membranes were prepared on asymmetric zirconia tubular support with an average pore size of 0.2 μm by hydrothermal method. The support should be pretreated with H 2 O as a pore-filling substance to prevent the sol solution from infiltrating into the support pores. The SEM showed that the MCM-48 membrane was composed of tightly-connected spherical crystal. The single gas N 2 and H 2 permeation experiments confirm that crack-free membrane could be prepared by pore-filling method. N 2 permeance of MCM-48 membrane, synthesized by secondary growth, can reach 5.66×10 −7 mol/Pa·s·m 2 , and the H 2 /N 2 separation factor was 3.47 under trans-membrane pressure of 0.05 MPa.

“…The physical properties of the MCM-48 membranes reported so far in the literature have only been defined to a limited extent. Indeed, in most publications, the material characterization has mainly focused on MCM-48 powders and not the MCM-48 membranes themselves [25,[33][34][35].…”
