Abstract:
A reactive sol-gel catalytic porous material comprising a mesoporous inorganic support and a sol-gel catalytic porous material coated on said mesoporous inorganic support, said sol-gel porous material comprising a copolymer ofa) 3-amino-propyl-trimethyloxysilane as a monomer precursor and b) a dopant consisting of 4-oxy-2,2,6,6-tetramethyl-1-piperidinyloxy as a stable nitroxyl radical or as a precursor thereof tethered to said monomer precursor through reductive amination, and c) at least one additive selected from those known to be useful in the preparation of porous materials to form a gel containing said dopant trapped therein.
