Abstract
Mesoporous silica is disclosed possessing a two-dimensional, hexagonal, through-hole structure with a space group p6mm, that is formed using one or more water-soluble oxidized disulfide oil (ODSO) compounds during the synthesis to impart distinct characteristics including an increased percentage of silanol groups.
Claims18
Mesoporous silica having hexagonal p6mm symmetry formed by the process of:
- mixing in an aqueous medium under conditions conducive to promote hydrolysis reactions effective quantities of
- a surfactant as a soft template material to influence a silica mesoporous structure,
- one or more water-soluble oxidized disulfide oil (ODSO) compounds as an acidity modifier, and
- a silica source;
- heating the mixture under conditions and for a time effective conducive to promote condensation reactions and to form mesoporous silica as a precipitate suspended in a supernatant as an intermediate suspension;
- and
- recovering the mesoporous silica from the intermediate suspension.
