Micro - and mesoporous materials have gained increased interest over the last decades, due to their variety of tuneable properties. This review presents ordered mesoporous silica (OMS), periodic mesoporous organosilicas (PMOs), zeolites, metal organic frameworks (MOFs) and covalent organic frameworks (COFs) as the most relevant and investigated groups of porous and solid materials as solid state proton conductors. Their high specific surface area is the ideal playground for introducing very acidic sulfonic acid groups, in order to form solid state acids. The sulfonic acid functionalization of these type of materials leads to their applicability in catalysis and proton conduction applications, e.g. in proton-conducting membranes of fuel cells or electrolysers. Herein, current sulfonation methods for porous materials are summarized and the resulting enhancement effect on proton conductivity is presented.

多孔材料的磺化及其质子传导性

在过去的几十年中,微孔和中孔材料由于其可调节的特性而引起了越来越多的兴趣。这篇评论介绍了有序介孔二氧化硅(OMS),周期性介孔有机二氧化硅(PMO),沸石,金属有机骨架(MOF)和共价有机骨架(COF)是与多孔质和固态材料作为固态质子导体最相关和研究最多的一组。它们的高比表面积是引入极酸性磺酸基团以形成固态酸的理想场所。这些类型的材料的磺酸官能化导致它们在催化和质子传导应用中的适用性,例如在燃料电池或电解器的质子传导膜中。在这里
