Abstract:
The invention provides superficially porous metal oxide or hybrid metal oxide monoliths with ordered pore structures. The superficially porous hybrid silica monoliths of the invention provide several major advantages over existing silica monoliths. When used in chromatography, the superficially porous hybrid silica monoliths of the invention deliver fast separation at very low back pressure and possess superb pH stability and much improved mechanical strength.
Abstract:
The present invention is a process for making an inorganic/organic hybrid totally porous spherical silica particles by self assembly of surfactants that serve as organic templates via pseudomorphic transformation.
