High Content Of Zirconium Amount Of Mesoporous Molecular Sieves Synthesis And Dielectric Kong Chaoqiang Acid Catalyst Of The Study

Mesoporous and macroporous materials have attracted more and more attentions world widely since they were synthesized in 1990' s, due to their excellent characters, such as bigger pore size, larger surface area, being easier to modify than microporous materials, and their potential application as catalysts and sorbents in industry. The researches about their synthesis, catalytic characters, and characterizations have been a very important subject in catalysis area.Recently superacidic mesoporous molecular sieve is appeared as a novel catalytic material, which possesses the characteristics of high surface areas, controlled pore structures, good thermal stability and super acid, and so it can be possibly applied to the industry. Therefore, Superacidic mesoporous molecular sieve is the worthwhile subject among the researches on the solid acid catalysts.It can improve the performances of mesoporous molecular sieve, and whereas lower inerratic orders of mesoporous structure somewhat by incorporating transition metal into framework. So, among the researches on the modification of molecular sieves, it is an important problem to embed as more transition metals into molecular sieve as possible with the protection of primary structure.Mesoporous materials synthesized with the template of nonionic poly(ethylene oxide)- poly(propylene oxide)- poly(ethylene oxide) block copolymers (Pluronic, EOyPOxEOy) were commercial, cheap and innocuity. It satisfied the need of economy and entironment. Ours have used microwave method and EO₁₀₀PO₇₀EO₁₀₀ for the synthesis of SBA-16.
