Fine control of pore size of highly ordered MCM-41 by using template mixtures of dodecyltrimethylammonium bromide/hexadecyltrimethylammonium bromide with various molar ratios

摘要

MCM-41 materials were prepared hydrothermally by using template mixtures of hexadecyltrimethylammonium/dodecyltrimethylammonium (C(16)TMABr/C(12)TMABr) with various molar ratios. The MCM-41 materials thus prepared were highly ordered and their pore sizes can be finely controlled by changing the C(16)TMABr/C(12)TMABr molar ratio. [References: 5]
