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。
Among the family of ordered mesoporous materials, SBA-15 is attracting much attention due to its large pore size, regularly-adjustable pore structure, and excellent mechanical and hydrothermal stability. Recently, the SBA-15 sheet / plate short hole has become a hotspot in the field of mesoporous materials due to the fact that SBA-15 is more favorable to the rapid diffusion and mass transfer of molecules. At present, the main methods of synthesizing the SBA-15 film / plate short hole are organic-assisted, metal ion-induced and synergistic effect of multiple templates. According to the mechanism of action of different kinds of additives, this paper reviewed the control synthesis methods of SBA-15 / SBA-15 and its recent progress in different fields such as catalysis, adsorption and biomolecule immobilization. The prospect of its application was also reviewed.
