    • A process for preparing a 2D-hexagonal ordered mesoporous silica material with a substantially uniform pore size in the range of 4 to 30 nm comprising the steps of: preparing an aqueous solution comprising an alkali silicate solution; preparing an aqueous solution comprising a poly(alkylene oxide) triblock copolymer and a buffer with a pH greater than 2 and less than 8, adding said aqueous alkali silicate solution to said aqueous solution giving a pH greater than 2 and less than 8 and allowing a reaction between the components to take place at a temperature in the range of 10 to 100° C., and filtering off, drying and calcinating the reaction product to produce said 2D-hexagonal ordered mesoporous silica material with a substantially uniform pore size. In an alternative procedure both aqueous solutions are fed as liquid streams into an elongated mixing receptacle having a first and a second opening such that the liquid streams of the solutions are each discharged independently into said first opening of said elongated mixing receptacle such that they directly impinge thereby giving a pH in the resulting mixture of greater than 2 and less than 8 and producing a reaction product at a temperature in the range of 10 to 100° C. in said elongated mixing receptacle, which upon emergence from said second opening of said elongated mixing receptacle is filtered off, dried and the surfactant removed.
    • 一种制备具有4至30nm范围内基本均匀孔径的二维六方有序介孔二氧化硅材料的方法,包括以下步骤:制备包含碱金属硅酸盐溶液的水溶液; 制备包含聚(环氧烷)三嵌段共聚物和pH大于2且小于8的缓冲液的水溶液,将所述碱性硅酸钠水溶液加入到所述水溶液中,得到大于2且小于8的pH,并允许 组分之间的反应在10至100℃的温度下进行,并过滤掉,干燥和煅烧反应产物以产生具有基本均匀的孔径的所述二维六方有序介孔二氧化硅材料。 在另一种方法中,两种水溶液以液体流的形式进入具有第一和第二开口的细长混合容器中,使得溶液的液体流各自独立地排放到所述细长混合容器的所述第一开口中,使得它们直接冲击 从而在所得混合物中产生大于2且小于8的pH,并在所述细长混合容器中在10至100℃范围内的温度下产生反应产物,在从所述细长的第二开口出来时, 将混合容器滤出,干燥并除去表面活性剂。
