The development of efficient electrocatalysts towards oxygen evolution reaction (OER) is critical for large-scale applications of electrochemical water splitting and metal-air cells. Usually, transition metal alloys exhibit superior activity for OER. Herein, we successfully prepared a series of scalable transition metal alloys with homogeneous size by a facial sol-gel self-propagating combustion method. Among them, the CoFe alloy displayed the highest oxygen evolution reaction (OER) activity, achieving an overpotential of 310 mV at 10 mA cm À 2 . After running OER tests for 48 h, the activity of CoFe alloy hardly decayed, indicating its outstanding stability. This work may make some contributions to the production of promising transition metal alloy catalysts and related energy equipment applications.

“…For the development of durable fuel cells, the search for electrocatalysts with superior efficiencies is therefore a significant hurdle. More recently, MOFs have been attractive for ORR applications [38][39][40] where the use of metal ions or clusters and organic connectors can aid the PEMFC technology can be made more efficient by using MOF materials that possess appropriate physical and chemical properties. The most commercially studied and applied proton-exchange membranes are composition-based nafion membranes.…”

The porous structure of MOF electrocatalysts facilitates mass transfer in electrochemical reactions, and as a result of the uniform distribution of metal throughout the MOF precursors, the active sites of the catalyst are efficiently utilized [41][42][43][44].…”

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.

“…Thus, MOFs are always used as precursors to produce porous nanostructured materials by thermal treatment under high temperature in controllable atmosphere, which is quite effective for heterogeneous catalysis. [18][19][20][21][22] Guo et al reported that bifunctional Fe 3 C@NCNT/NPC catalysts were successfully synthesized by one-pot heat treating melamine-loaded Fe-based MOF, and they exhibited excellent catalytic activity in OER and ORR. [23] Zhou et al synthesized magnetic Co 3 O 4 /CNTs obtained by thermal treating of Zn/Co MOFs, which exhibited outstanding catalytic performances for oxytetracycline degradation.…”

Novel and efficient ultrafine metallic cobalt nanoparticles encapsulated in N‐doped carbon catalysts are prepared via a facile method from pyrolysis of ZIF‐67‐x%CTAB, which is modified by CTAB (cetyltrimethyl ammonium bromide). The content of surfactant CTAB can control the crystal size of ZIF‐67, which further determines the Co particle size of Co@CN‐x%CTAB. The as‐prepared ZIF‐67‐x%CTAB and Co@CN‐x%CTAB were characterized by X‐ray powder diffraction (XRD), scanning electron microscopy (SEM), high‐resolution transmission electron microscopy (HRTEM), Brunauer−Emmett−Teller (BET), and X‐ray photoelectron spectroscopy (XPS). Co@CN‐0%CTAB could not maintain the primary morphologies of ZIF‐67‐0%CTAB with the collapse of skeleton. However, the Co@CN‐3%CTAB and Co@CN‐5%CTAB catalysts inherit the original morphologies with skeleton constriction. It indicated that Co@CN catalysts could maintain the skeleton structure of ZIF‐67 by adding CTAB during the preparation process. The particle size of Co@CN decreased with the increasing of CTAB content. Moreover, the addition of CTAB facilitated the formation of Co‐Nx species on catalyst surface. The kinetic rate constant of Co@CN‐5%CTAB catalyst was 0.99 min−1, which is 2.5 times as high as that of Co@CN‐0%CTAB catalyst for 4‐nitrophenol reduction. The excellent catalytic performance of Co@CN‐5%CTAB may be due to the presence of Co (0) species generated in situ during the calcination process, the smaller Co nanoparticles and more Co‐Nx site on the surface of the catalyst.
