Application of UiO-66 Series MOFs in Proton Exchange Membranes
Metal-organic frameworks (MOFs) are emerging proton-conducting materials widely used in the modification of proton exchange membranes (PEM). Among them, the UiO-66 series MOFs (UiO-MOFs) exhibit high thermal and chemical stability, and are easy to synthesize and modify, making them ideal for PEM modification. This paper primarily reviews related research on UiO-MOFs used for PEM modification over the past five years from the perspective of filler design and preparation. Section II introduces the materials and proton conduction mechanisms of UiO-MOFs. Section III summarizes the design of ligands and metal clusters in UiO-MOFs, such as acid/base group modifications and metal cluster replacements. Section IV consolidates the methods for post-synthetic modifications of UiO-MOFs, such as grafting acid/base groups using active functional groups from external crystal structures. Section V presents various composite schemes involving UiO-MOFs and other materials to construct composite fillers with different dimensionalities. Finally, the summary highlights unresolved issues regarding the use of UiO-MOFs in PEMs and proposes future research directions.
