Abstract

Abstract : The introduction of a sulfonate group can increase the hydrophilicity of the material and form an efficient proton conduction pathway to promote the proton conductivity of the material. Abstract : Introducing sulfonic acid groups into MOF materials is one of the effective approaches to enhance proton conduction. Here, we attempted to prepare a new post-modified ZIF-90-based material by addition reaction of the aldehyde group with bisulfite to obtain partially functionalized ZIF-90-SO3 Na(2.3) . ZIF-90-SO3 Na(2.3) exhibits a high proton conductivity of 2.26 × 10 −2 S cm −1 at 98% RH and 100 °C.
