CsHSO4 - Proton conduction in a crystalline metal-organic framework

► Proton conductors based on CsHSO4 and crystalline metal -organic framework. ► The new approach based on combining metal-organic frameworks and functional gests from acid salt family has been proposed. ► Transport, structural and thermodynamic properties of proton nanocomposites based on Cr MIL -101 and CsHSO4 have been investigated first.
