In the early 1990s, Mobil scientists and Japanese scientists separately reported the synthesis of mesostructured silicates that possess large uniform pore sizes (1.5-10 nm) high ordered nanochannels, large surface areas (∼ 1500 cu m/g) and attractive liquid crystal structures. These characteristics offer mesoporous molecular sieves good opportunities in hydrogen storage, catalysis, etc. A discussion covers the surfactant-templating approach for the synthesis of ordered mesoporous molecular sieves; synthesis pathways; corresponding mechanisms; key factors for the synthesis including the selection of surfactants, hydrothermal method, EISA strategy, the control of mesostructures, and the adjustment of pore sizes and morphologies; and applications of mesoporous materials.
