“…In addition, those nanostructures that emerge from MOF-derived SACs have excellent active-site support and excellent dispersion properties when applied to electrocatalytic processes. High absorbent properties that persist and are likely better controlled in self-removable supports deliver porous, hollow, structurally defined cavities [51][52][53][54]. According to the results of our study, MOF-designed electrocatalysts for fuel cells are capable of improving their working durability and have the potential to replace precious metals as costly conventional materials.…”

Metal-organic frameworks (MOFs) are arguably a class of highly tuneable polymer-based materials with wide applicability. The arrangement of chemical components and the bonds they form through specific chemical bond associations are critical determining factors in their functionality. In particular, crystalline porous materials continue to inspire their development and advancement towards sustainable and renewable materials for clean energy conversion and storage. An important area of development is the application of MOFs in proton-exchange membrane fuel cells (PEMFCs) and are attractive for efficient low-temperature energy conversion. The practical implementation of fuel cells, however, is faced by performance challenges. To address some of the technical issues, a more critical consideration of key problems is now driving a conceptualised approach to advance the application of PEMFCs. Central to this idea is the emerging field MOF-based systems, which are currently being adopted and proving to be a more efficient and durable means of creating electrodes and electrolytes for proton−exchange membrane fuel cells. This review proposes to discuss some of the key advancements in the modification of PEMs and electrodes, which primarily use functionally important MOFs. Further, we propose to correlate MOF-based PEMFC design and the deeper correlation with performance by comparing proton conductivities and catalytic activities for selected works.

“…[6,7] Crucially, functionalized MOFs showing proton conductivity can be utilized as ionselective membranes for fuel cell applications. [8,9] However, to achieve practical MOF-based membranes for applications in fuel cells or batteries, stability is key. [10] Therefore, Zr-based MOFs, the so-called UiO series (here, UiO indicates the University of Oslo, where these MOFs were first developed), have been widely utilized because of their relatively good chemical and physical stabilities.…”

Zr-based metal-organic frameworks (MOFs) were modified with pendant tetrazole ligands for proton conductivity studies. Although tetrazolate ligands coordinated to metal cations have been widely utilized to construct MOFs or porous coordination polymers, to date, the use of uncoordinated tetrazole groups in MOFs has been limited. In this study, a benzene-1,4-dicarboxylic acid with pendant tetrazole groups (BDC-N 4 ) was synthesized and used to prepare a Zr-based UiO-66 MOF using a mixed-ligand strategy. The tetrazolefunctionalized UiO-66-N 4 was compared to MOFs containing other acidic functional groups (hydroxyl, carboxylic acid, and sulfonic acid) with respect to their proton conductivities and acidities (calculated pK a ). Interestingly, UiO-66-N 4 showed a significant decrease in the activation energy with increase in the amount of added tetrazole groups, suggesting the Grotthuss proton conduction mechanism for uncoordinated tetrazole-containing MOFs.
