QENS Analysis of Proton Diffusion in Functional Metal-Organic Frameworks

DOI

The development of new functional metal-organic frameworks (MOFs) as complex proton conductor is receiving increasing attention worldwide. We aim to develop new solid proton conductors based upon stable MOFs and request 9 days on IRIS to study the motion of active protons in three isostructural porous MOF materials [MFM-300(M), M= Cr, Al and In] as a function of temperature. This proposed study will investigate the diffusion properties exhibited by these active protons from the MOF hosts. These three MOFs exhibit distinct proton conductivity (10-3 to 10-7 S cm-1 at 20 oC under 99%RH), although they have the same crystal structures, indicating the metal ions have significant impacts on the acidity of the MOF hosts. The proposed study aims to reveal the full nature of the proton conductivity by analysing the QENS data together with our MD modelling studies.
