Ln⁃MOF质子传导材料研究进展

Research Progress of Ln⁃MOF as Proton Conducting Material

质子传导材料是传感器和燃料电池的重要组成部分,近年来人们对晶态质子传导材料的研究主要集中在金属有机框架材料(MOF)方面。镧系金属有机框架(Ln⁃MOF)是MOF家族的重要一员,镧系离子因具有较强的配位能力、路易斯酸性和复杂的功能性,容易形成稳定的多样性骨架。对主体骨架中引入不同功能性酸基团(羧酸、膦酸或磺酸基团等)的Ln⁃MOF材料在质子传导方面的研究进展进行综述,并对Ln⁃MOF材料在质子传导研究中面临的挑战做出展望。

Proton conductive materials are an important part of sensors and fuel cells.In recent years,the research of crystalline proton conducting materials has mainly focused on metal organic framework material(MOF).Lanthanide metal organic framework(Ln⁃MOF)is an important member of the MOF family,and it is easy to form a stable and diverse framework owing to the strong coordination ability,Lewis acidity and complex functionality of lanthanide ions.At present,people are beginning to focus on its research in the field of proton conduction.This article reviews the research progress in proton conduction of Ln⁃MOF materials with different functional acid groups(carboxylate,phosphonate or sulfonate groups,etc.)introduced into the main frame.The challenges faced by Ln⁃MOF materials in the study of proton conduction were prospected.
