| Popis: | Novel modified catalyst carriers have been prepared. First, aminopropyltriethoxysilane (APTES) was immobilized on the silica surface by using the saturated gas–solid reactions. Secondly, two different (tetramethylcyclopentadienyl)chlorosilanes, (Me2Si(C5Me4H)Cl and MeHSi(C5Me4H)Cl), were synthesized and anchored on the amine surface using liquid-phase reactions. Characterization of these stepwise prepared surfaces was carried out by 1 H , 13 C and 29 Si solid state NMR and FTIR spectroscopy. |
