The modification of the surface of the gallophosphate cloverite by adsorpti
on of various silane compounds has been investigated. By using XRD, thermal
analysis, FTIR and H-1 MAS NMR spectroscopy it is shown that, in principle
, the structure of cloverite call be stabilized at ambient conditions. Howe
ver, it became obvious that the accessible pore volume strongly depends oil
the amount and size of the silanes adsorbed oil the surface.
