We report novel routes for synthesis of defect‐free, hydrophobic and monodispersed 10 nm (5 unit cells) thick MFI crystals and 100 nm CHA crystals. The crystals are obtained in high yield and display very high 1‐butanol adsorption from aqueous solution. These crystals are assembled in monolayers for the growth of ultrathin and uniformly oriented films with thicknesses of 36 nm and 330 nm, respectively, using a synthesis gel in the form of a powder. This method is very simple and may open up for industrial preparation of materials with improved performances.

疏水性胶体MFI和CHA晶体及取向超薄膜的简便制备

我们报告了合成无缺陷，疏水和单分散的10 nm（5个晶胞）厚的MFI晶体和100 nm CHA晶体的新颖途径。晶体得率高，从水溶液中显示出很高的1-丁醇吸附率。使用粉末形式的合成凝胶，将这些晶体组装成单层，以分别生长厚度分别为36 nm和330 nm的超薄和均匀取向的薄膜。该方法非常简单，可以为性能改善的材料的工业制备开辟道路。
