Mesoporous Zirconium Silicate Catalysts Prepared by Non-hydrolytic Acetamide Elimination
Original language description
Non-hydrolytic sol-gel reactions are efficient alternatives to classical aqueous techniques for synthesis of multimetallic oxides and inorganic-organic hybrid materials. This process provides better reaction control and higher homogeneity of prepared materials. We developed non-hydrolytic sol-gel routes to several groups of metallosilicate materials and efficient catalysts based on acetamide elimination reactions (1,2). Our approach is based on the acetamide condensation reaction of silicon tetraacetateSi(OAc)4 and zirconium diethylamide Zr(NEt2)4 that leads to the formation of Si?O?Zr bonds in the xerogel framework (IR, 29Si CPMAS NMR). Diethylacetamide and acetanhydride were confirmed (GC-MS, 1H NMR) as the reaction byproducts. To achieve the mesoporous nature of the xerogels, the reaction was successfully modified by the addition of the Pluronic P123 template with structure-directing and protecting functions which allow to prepare stiff gels.
