Porous Hybrid Inorganic-Organic Silicophosphate Materials by Non-Hydrolytic Sol-Gel Polycondensation and Their Use as Solid Phosphoric Acid Catalyst
Original language description
Non-hydrolytic sol-gel reactions are viable alternatives to classical aqueous techniques in the area of synthesis of multimetallic oxides and inorganic-organic hybrid materials in the form of xerogels, nanoparticles, and thin films. We developed non-hydrolytic sol-gel route based on acetic acid ester elimination providing phosphosilicate hybrid inorganic-organic materials. The polycondensation reactions between Si(OAc)4 and OP(OSiMe3)3 lead to microporous phosphosilicate xerogels with surface areas up to 568 m2 g-1. The structure of xerogels was built up exclusively from Si-O-P bonds and contained octahedrally coordinated silicon atoms, which are characteristic for crystalline silicon phosphates.1 We changed starting precursors to acetoxysilanes and phosphonic acid esters with bridging alkyl or aryl groups (AcO)3Si-(CH2)x-Si(OAc)3 (x = 1-3, 6), (Me3SiO)2P(O)-3R-P(O)(OSiMe3)2 (3R = C2H4, C6H4).
