Description
Technical field
The present invention relates to a kind of mesoporous material, particularly relate to a kind of ordered meso-porous material, and the preparation method of this mesoporous material.
Background technology
Mesoporous silicon oxide is the cellular solid of a kind of aperture 2-50nm.Since Mobile company synthesizes after M41S series mesoporous material for 1992 first, because it has that pore passage structure is regular, big or small adjustable, the specific surface area in duct compared with large, hydrothermal stability compared with high, absorption pore volume compared with the advantage such as large, pattern is different people's extensive concern extremely.Except possessing above advantage, also because of it, there is the meso-hole structure of 2 kinds of different pore sizes, and there is its unique performance in double-mesoporous material.For example large mesoporous larger because of aperture in double-mesoporous material, so diffusional resistance is less, can be used as the transport passage of reactant and product, also can reach the selection translocation to material by regulating and controlling its structure; Little mesoporous because of the selectivity that its active sites is more, specific surface is large, catalysis has been had, thereby the place that can be used as reactant absorption and react.Double-mesoporous material, owing to having above advantage, makes it at aspects such as catalyzer preparation, medicine, Controlled Release Fertilizers, have huge potential application.
Order mesoporous synthesizing is generally synthetic by supramolecule self-assembling method, obtains the organic-inorganic composite body that specific Jie sees space structure, then removes tensio-active agent by the method for roasting or extraction, thereby obtain mesoporous material.The supermolecular module agent of the most generally using is nonionic surface active agent, and using hydrochloric acid as solvent (D.Zhao, J.Feng, Q.Huo, et al. Science, 1998,279,548), but by this method single, the aperture of the meso-porous titanium dioxide silicon structure of preparation only has a kind of, the material that cannot synthesize a plurality of apertures, makes it in catalyzer use, have certain defect.The document of preparing of diplopore and multilevel porous structure mesoporous material is also reported to some extent, be mainly other microcosmic by having prepared before adding when synthesising mesoporous or the macropore or be situated between and see material and make its parcel, and then prepare porous structure material (P. Yang, T. Deng, D. Zhao, Science, 1998,282,2244).This preparation method's step is complicated, aperture adjustment is limited, and processing requirement is high, duct order is poor.Thereby, by simple step, synthesize the mesoporous silicon oxide of multilevel ordered pore structure, so far or a popular research topic.
