HYDROTHERMOSTABILITY OF MESOPOROUS MESOPHASE MATERIALS OF MCM-41 AND SBA-3 TYPE

A method of silica mesoporous mesophase material (MMM) of SBA-3 type hydrothermostability (HTS) improvement by its post-synthesis hydrothermal treatment (HTT) in ammonia solution has been investigated. The effects of treatment duration and ammonia concentration on the structural and textural parameters of MMM have been determined. A mechanism of MMM transformation under HTT conditions is suggested.
