摘要
有序介孔材料家族中,SBA-15因具有较大的孔径尺寸、规则可调的孔道结构以及卓越的机械和水热稳定性而备受关注。最近,片/板状短孔道SBA-15由于更有利于分子快速扩散和质量传递成为介孔材料研究领域的热点。目前合成片/板状短孔道SBA-15的主要方法有有机物辅助、金属离子诱导及多重模板剂协同效应。根据不同类别添加剂的作用机制,本文综述了片/板状短孔道SBA-15的控制合成方法及其在催化、吸附和生物分子固定等不同领域的最新进展,并对其应用前景进行了展望。
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 cosolvent effect of alkane molecules, inducing effect of metal ions and syngeristic effect of multisurfactants. 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.
