    Abstract: Cubic mesoporous silicas having substantially cylindrical morphology may be prepared using a combination of a first structure-directing template, such as tetramethyl ammonium hydroxide; water; a second structure-directing template, such as cetyltrimethylammonium bromide; a morphology-directing template, such as a poloxamer having a weight average molecular weight ranging from 5,000 to 20,000 Daltons; and a silica source; in the substantial absence of an alcohol solvent. The resulting materials may exhibit a three-dimensional channel structure, a length from 3 to 10 micrometers and a width from 300 nanometers to 10 micrometers, resulting in an aspect ratio from 1 to 300. Further characterization may include a surface area from 1300 to 1500 square meters per gram, an average pore diameter from 20 to 26 angstroms, and an average pore volume ranging from 0.7 to 1.1 cubic centimeters per gram. These materials are useful for molecular transport and release applications in a variety of uses, including, for example, membrane separations, metal incorporation, electronic devices, drug delivery, and adsorption.

    Abstract: A process for preparing a mesoporous silica comprising contacting as starting components (1) a structure-directing template selected from the group consisting of hydrogenated and non-hydrogenated natural vegetable oils, silicone oils, and combinations thereof; (2) water; (3) silica; and, optionally, (4) a structure-directing co-template selected from tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, cetyltrimethylammonium bromide (CTAB), hexadecyltrimethylammonium chloride; hexadecyltrimethylammonium hydroxide hydrate, hexadecyltrimethylammonium p-toluenesulfonate, hexadecyltrimethylammonium bis-sulfonate, poloxamers having a weight average molecular weight ranging from 5,000 to 20,000 Daltons (Da), and combinations thereof; in the substantial absence of an alcohol solvent; under conditions such that a mesoporous silica having an average pore diameter ranging from 50 to 175 angstroms and a pore diameter distribution that, within one standard deviation of its mean, is substantially unimodal, is formed. The product composition may offer preferred use in, for example, gas separations, sensing, water purification, heavy metal removal, and electronics, where its narrower pore diameter distribution increases its selectivity.
