NMR provides checklist of generic properties for atomic-scale models of periodic mesoporous silicas

Article Abstract:

A study was conducted to determine generic structural parameters of MCM-41 and SBA-15 type ordered mesoporous silicas that could be used as a checklist for atomic-scale structural models. The number of silanol groups at a given MCM-41 and SBA-15 silica were found to increase after treatment with C[H.sub.3]Si[(OH).sub.3] reagent while all surface silanol groups were found to be functionalized on treatment with HN[(Si[(C[H.sub.3]).sub.3]).sub.2].

Microcrystallization of benzene-d(sub 6) in mesoporous silica revealed by (super 2)H solid-state nuclear magnetic resonance

Article Abstract:

A study is conducted to examine the benzene-d6 confined in a mesoscopically organized, controlled, porous-glass mesocellular foam with the help of low-temperature solid-state (super 2)H nuclear magnetic resonance spectroscopy in the temperature range of 90-180 K. The resulting spectra are compared to bulk benzene-d6 and benzene confined in mesoporous silica.
