以三脚架胆酰胺水凝胶为模板合成了无机纳米管。除二氧化硅、二氧化钛、氧化锆、氧化钨和氧化锌等氧化物纳米管外，还制备了硫酸盐纳米管、水溶性硫酸锌纳米管和硫酸钡纳米管。使用该水凝胶的一个优点是，合成氧化物纳米管不需要金属醇盐。用X射线衍射仪和透射电子显微镜对纳米管进行了表征。
A tripodal cholamide-based hydrogel has been employed as a template to synthesize inorganic nanotubes. Besides nanotubes of oxides such as SiO2, TiO2, ZrO2, WO3 and ZnO, nanotubes of sulfates such as the water-soluble ZnSO4 as well as of BaSO4 have been obtained using this method. An advantage of the use of the hydrogel is that metal alkoxides are not required for the synthesis of the oxide nanotubes. The nanotubes have been characterized by X-ray diffraction and transmission electron microscopy.
