摘要
改性蒙脱土是近年来受国内外学者广泛关注的矿物材料之一,由于其层间的特殊结构而被广泛应用于吸附、催化等领域。概括介绍了蒙脱土的结构和基本性质,重点讨论了蒙脱土改性方法和机理。对无机改性、有机改性和有机-无机复合改性分别作了论述,并展望了其应用前景。
Modified montmorillonites have been proved to be one of the most interesting mineral materials used in adsorption, catalysis and catalytic supports, photocatalysis and so on. The pillared montmorillonite interlayer is a special site in chemical reaction. The structure and elementary property of montmorillonite were introduced in this paper, and the modifying methods and mechanism were emphatically discussed. Advance in modification of montmorillonites, including inorganic modification, organic modification and inorgano-organo-modification was summarized. And the existing problems and applying prospect of modified montmorillonites were proposed.
