    • A method for the preparation of new quasi-crystalline, porous inorganic oxide materials possessing uniform framework-confined mesopores in the range 2.0-10.0 nm and large elementary particle size of more than 500.0 nm. The method uses an interaction between various non-ionic polyethylene oxide based surfactants (N°) and neutral inorganic oxide precursors (I°) at ambient reaction temperatures. The materials formed exhibit semi-ordered arrays of well defined pores owing to the specific mechanism of self-assembly, large pore wall thicknesses of at least 2.0 nm producing highly stable materials and large particle sizes incorporating large numbers of pores. This (N° I°) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.
    • 一种制备新型准晶体多孔无机氧化物材料的方法,该材料具有2.0-10.0nm范围的均匀骨架介孔和大于500.0nm的大基本粒度。 该方法在环境反应温度下使用各种基于非离子聚环氧乙烷的表面活性剂(N°)和中性无机氧化物前体(I°)之间的相互作用。 由于自组装的特殊机制,形成的材料具有半有序的阵列,具有至少2.0nm的大孔壁厚度,产生高度稳定的材料和具有大量孔隙的大粒径。 这种(N°I°)模板方法为介观结构合成引入了几个新概念。 低成本,无毒且可生物降解的表面活性剂和环境反应温度的应用,引入了环境清洁的合成技术来形成中间结构。 通过溶剂萃取可以实现模板的回收,其中溶剂可以是水或乙醇。
