| Abstract: | ![]()
The formation of siliceous mesoporous mesophase materials (SiO2-MMM) prepared by precipitation of soluble forms of SiO2 with alkyltrimethylalkylammonium bromide C n TMABr (n=12, 14, 16, 18 is the number of carbon atoms in the alkyl chain) was investigated. An increase in then value has no influence on the mechanism of formation of SiO2-MMM but causes an increase in the size and volume of mesopores with the mesopore specific surface area and wall thickness remaining virtually constant. |
