Advances in Mesoporous Silica Morphologies Dang Wenxiu, Han Shuhua, Hou Wanguo*, Xu Jun, Yan Xin (Key Laboratory of Colloid and Interface Chemistry, Ministry of Education, (Shandong University) Jinan 250100) Abstract A variety of morphologies of mesoporous silica, such as sphere, rod, fiber, helicoid, hollow tubule and other radial patterns, can be synthesized by using surfactants as templates in either alkaline or acid solution. The formation of particular morphology depends on the experimental conditions of synthesis, including surfactant, cosolvent, precursor, counterions, acidity, temperature and so on. Several morphogenesis mechanisms, such as supramolecule origami mechanism, geometric matching mechanism, singularity-fluctuation mechanism and defect effect mechanism, are proposed in recent years. The latest advances in the particular morphology of silica-based mesoporous materials are summarized in this paper.
