Reaction of Surface Hydroxyl Group of MCM41 with Tetraneopentylzirconium
Abstract:
ZrNp4 could react at room temperature with surface hydroxy groups of MCM41 molecular sieve, with formation of an organozirconium complex (≡Si－O)2Np2 on the surface. The method of preparation of the surface complex is presented. The effects of the reaction temperature, of the sublimation temperature of ZrNp4 and of the dehydration temperature of MCM41 on the preparation were investigated. The composition and structure of the surface complex were characterized by FTIR, solid state MAS NMR and chemical probe reaction.
