Two groups of amine-functionalized organosilicas have been synthesized: amorphous polysiloxane xerogels (APX) and ordered mesoporous organosilicas (OMO) by co-condensation of tetraethoxysilane and appropriate alkoxysilanes: aminopropyltriethoxysilane and N-[3-(trimethoxysilyl)propyl]ethylenediamine. The obtained materials were characterized by sorption measurements, X-ray diffractometry, elemental...
SBA-15 organosilicas containing amine, thiol, vinyl and phenyl pendant groups were synthesized by co-condensation of tetraethoxysilane and appropriate alkoxysilanes in the presence of Pluronic P123 surfactant. The obtained materials have usually well-developed porous structure—values of specific surface area are in the range 820–950 m2/g. Sizes of the ordered mesopores are in the range 7.5–9.1 nm...
