摘要

了解层状双氢氧化物（LDHs）中的离子传导是将其作为固态氢氧根离子传导电解质用于能量转换应用的关键一步。我们用三（羟甲基）氨基甲烷（TRIS）配体选择性地修饰了 MgAl LDHs 的层间和外表面。通过调节 TRIS 表面改性剂的浓度，可以对 LDH 基底面的所有表面（内部和外部）进行功能化，也可以仅对其进行外部功能化。与原始 LDH 相比，外部修饰会导致 OH 传导性的丧失，这证实了血小板的外部表面是离子传导的主要途径。

Selective Covalent Basal Plane Modification as a Probe of Hydroxide Ion Conduction Pathways in Magnesium Aluminum Layered Double Hydroxides

Understanding ionic conduction in layered double hydroxides (LDHs) is a crucial step towards utilizing them as solid, hydroxide ion-conducting electrolytes in energy conversion applications. We selectively modified the interlayer and external surfaces of MgAl LDHs with tris(hydroxymethyl)aminomethane (TRIS) ligands. By adjusting the concentration of the TRIS surface modifier, the LDH basal plane surfaces could be functionalized everywhere (internally and externally) or only externally. External modification resulted in loss of OH-conductivity compared to pristine LDHs, confirming that external platelet surfaces are the primary ion conduction pathway.
