Coconstruction of MOF/CNT-Based Interconnected Acid-Base Pair Hybrid Materials for Improved Performance in Proton Exchange Membranes.

ABSTRACT: UiO-66-NH₂ and UiO-66-SO₃H, which are fine proton conductors, have been extensively applied in the construction of composite proton exchange membranes, owing to their good thermal and chemical stabilities, easy functionalization, and an ideal source of acid-base pairs. In this study, an interconnected acid-base pair hybrid (UNSC, UiO-66-NH₂/-SO₃H-CNTs) was synthesized via the in situ cogrowth of UiO-66-NH₂ and UiO-66-SO₃H on carbon nanotubes (CNTs). The resulting continuous arrays of acid-base pairs promote the formation of ordered proton-transport channels and increase the density of proton-conducting sites, while the CNT-supported hybrid enhances particle dispersion and mechanical strength. Consequently, the achieved SPEEK
