Abstract
V originále
Non-hydrolytic sol-gel reactions [1] are used for the synthesis of multimetallic mesoporous oxide catalysts [2], crystalline nanoparticles [3], and hybrid materials [4]. They are alternatives to classical aqueous techniques. We developed non-hydrolytic sol-gel routes based on acetamide and acetic acid ester elimination providing aluminosilicate and –phosphate materials and related hybrid inorganic-organic materials. The polycondensation reactions between Al(NMe2)3 and Si(OAc)4 lead to aluminosilicates and the reactions of Al(NMe2)3 or AlCl3 with OP(OSiMe3)3 lead to porous aluminophosphate xerogels with high surface areas (up to 1000 m2 g-1). The structure of xerogels is built from Si-O-Al and Al-O-P bonds. We used pore generating agents, such as Pluronic P123 and F127 added into the reaction mixture during gelation to produce mesoporous xerogels. After burning out of templates at 500 oC the samples are mesoporous with surface areas above 400 m2 g-1. The prepared xerogels and calcined samples were characterized by solid-state 13C, 27Al, 29Si, 31P NMR, IR, surface area analysis, TGA, SEM, and XRD.
