QENS Study of Proton Conducting Metal-Organic Framework Materials

Abstract: The development of new functional metal-organic frameworks (MOFs) is receiving considerable attention worldwide owing to their potential for gas storage, ionic conductivity, and catalysis. We seek to develop new solid proton conductors based upon MOFs and request 5 days on IRIS to study the motion of active protons in two functional porous MOF materials [NOTT-500(Co,Ni)]. This proposed study will investigate the diffusion properties exhibited by these active protons from the MOF hosts. These two MOFs exhibit high proton conductivity (4.5 x 10-4 Scm-1 at 25 oC under 98%RH), and QENS study on the dry sample has suggested a “spherical free diffusion” mechanism for proton transfer within the framework lattice, representing the first example of such in MOFs. The proposed study aims to reveal the full nature of the proton conductivity by analysing the QENS data of wet sample under 98%RH.
