A novel dual-template strategy was first proposed for the fabrication of mesoporous silica with hollow triangular prism morphology, using amino acid ionic liquid tetramethylammonium glycine ([N₁₁₁₁][Gly]) and supramolecular organogel N-lauroyl-l-glutamic acid di-n-butylamide (GP-1) as the cotemplate. The influence of aging time and the ratio of different templates on the morphology of the synthesized silica was studied. Compared to the silica spheres synthesized using [N₁₁₁₁][Gly] as template and irregular blocks obtained using only GP-1 template, the hollow triangular prism-like mesoporous silica tube with uniform morphology and high specific surface area was constructed under the optimal conditions within the ionic liquid–supramolecular gel cotemplate. Moreover, the cotemplate mechanism on how to control the microstructure of mesoporous silica was discussed in depth.

离子液体-超分子有机凝胶共模板可控合成介孔二氧化硅

首次提出了一种新颖的双模板策略，该方法使用氨基酸离子液体四甲基铵甘氨酸（[N ₁₁₁₁ ] [Gly]）和超分子有机凝胶N-月桂酰-1-谷氨酸二-来制造具有空心三角棱柱形态的介孔二氧化硅。正丁基酰胺（GP-1）作为共模板。研究了老化时间和不同模板比例对合成二氧化硅形貌的影响。与使用[N _1111]合成的二氧化硅球相比以[Gly]为模板，仅使用GP-1模板获得不规则嵌段，在离子液体-超分子凝胶共模板的最佳条件下，构建了形态均匀，比表面积高的空心三棱柱状介孔二氧化硅管。此外，深入讨论了如何控制介孔二氧化硅微观结构的共模板机制。
