With the global energy demand expected to increase drastically over the next several decades, the development of a sustainable energy system to meet this increase is paramount. Renewable energy sources can be coupled with electrochemical conversion processes to store energy in chemical bonds. To promote these difficult transformations, electrocatalysts that operate at high conversion rates and efficiency are required. Metal–organic frameworks (MOFs) have emerged as a promising class of materials; however, the insulating nature of MOFs has limited their application as electrocatalysts. The recent development of conductive MOFs has led to several electrocatalytic MOFs that display activity comparable to that of the best‐performing heterogeneous catalysts. Although many electrocatalytic MOFs exhibit low activity and stability, the few successful examples highlight the possibility of MOF electrocatalysts as replacements for noble‐metal‐based catalysts in commercial energy‐converting devices. We review herein the use of pristine MOFs as electrocatalysts to facilitate important energy‐related reactions.

“…In the same year, Usov et al. reported a highly robust MOF named PCN‐223‐Fe by combining Zr 6 oxo clusters and Fe III porphyrin linkers, opening a new route to optimize MOFs as ORR electrocatalysts by selecting proton sources . These results exemplify that it is feasible to use ORR active complexes as the building blocks for preparing ORR‐active MOFs.…”

In view of the clean and sustainable energy, metal–organic frameworks (MOFs) based materials, including pristine MOFs, MOF composites, and their derivatives are emerging as unique electrocatalysts for oxygen reduction reaction (ORR). Thanks to their tunable compositions and diverse structures, efficient MOF‐based materials provide new opportunities to accelerate the sluggish ORR at the cathode in fuel cells and metal–air batteries. This Minireview first provides some introduction of ORR and MOFs, followed by the classification of MOF‐based electrocatalysts towards ORR. Recent breakthroughs in engineering MOF‐based ORR electrocatalysts are highlighted with an emphasis on synthesis strategy, component, morphology, structure, electrocatalytic performance, and reaction mechanism. Finally, some current challenges and future perspectives for MOF‐based ORR electrocatalysts are also discussed.

“…Upon adding weak Brönsted acids in the Fe_MOF-525 system, significantly enhanced current densities and better stability were observed. [183] The Zr 4 + ions of PCN-223-Fe with redox inertness play an important role in terms of structural stability and Fe play an essential role in promoting catalytic activity toward ORR. Similar to the study of Hod et al, Usov et al selected the same linkers, Fe(III) porphyrin, to link with Zr 6 oxo clusters, forming a heterogeneous catalyst PCN-223-Fe (Zr 6 O 4 (OH) 4 (Fe(III)-(TCPP) 3 , Figure 16b) with a highly stable structure for the electrocatalytic ORR in 2017.…”

Pristine metal‐organic frameworks (MOFs) and their composites, which have received wide attention in recent years, especially in the field of electrocatalysis, are emerging as distinctive electrocatalysts for the oxygen reduction reaction (ORR), hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), oxygen evolution reaction (OER), and many other electrochemical redox reactions. In this review, the attention is focused on the development of monometallic‐MOFs and multimetallic‐MOFs (including bimetallic‐MOFs and trimetallic‐MOFs) for electrocatalysis in recent years, including their design, catalytic performance and strategies for activity improvement. Finally, major challenges in utilizing pristine MOFs and their composites for electrocatalysis are highlighted.
