Ordered SBA-15 materials are of great importance in the materials field due to the tunable pore size within 5-30 nm and excellent mechanical and hydrothermal stability in comparison with other siliceous mesostructures. More recently, platelet SBA-15 with short channels have attracted great attention because of the favorable effect for molecular delivery and mass transfer. Platelet SBA-15 materials have been synthesized using various effective synthesis pathways including co-solvent effect of alkane molecules, inducing effect of metal ions and syngeristic effect of multi-surfactants. Based on different assembly mechanisms, the current progress in designed assembly and applications of platelet SBA-15 in catalysis, adsorption and biomedical molecule immobilization are reviewed, and the perceptive on potentiality of this newcomer with fascinating characteristics is also prospected.
