“…Hence, it is essential to find the cheaper alternatives that are more common, highly active, and stable 13 . In doing so, a key strategy to retrieve high‐performance OER catalysts hinges upon the availability of electrode materials, including carbon‐based nanomaterials, graphene, and metal oxides/selenides/sulfides 14–24 . Thus far, the scientific community is increasingly interested in porous nanostructure‐based electrode materials, given their high surface‐to‐volume ratio, large and well‐defined pore structure, and even distribution of available active sites.…”

Engineering cost‐effective catalysts with exceptional performance for the electrochemical oxygen evolution reaction (OER) remains crucial for the accelerated development of renewable energy techniques, and especially so, given the pivotal role of OER in water electrolysis. On the basis of the metal nodes (clusters) and organic linkers, metal‐organic frameworks (MOFs) and their derivatives are rapidly gaining ground in the fabrication of electrocatalysts, with promising catalytic activity and sound durability in OER, thanks to their controllable pore structures, abundant unsaturated active sites of metal ion, extensive specific surface area, as well as easily functionalized/modified surfaces. This review presents an in‐depth understanding of the established progress of MOFs‐derived materials for OER electrocatalysis. The material designing strategies of the pristine, monometallic, and multimetallic MOFs‐based catalysts are summarized to indicate the infinite possibilities of the morphology and the composition of MOF‐derived materials. While emphasis is laid on the essential features of MOF‐derived materials for the electrocatalysis of the corresponding reactions, insights about the applications in OER are discussed. Finally, this paper is concluded by presenting challenges and perspectives for MOF‐derived materials’ future applications in OER electrocatalysis.

“…28 The results indicated that the co-existence of Fe/Co N sites and core-shell structure could significantly promote the ORR. Nevertheless, the aforementioned catalysts were typically synthesized by using complicated heat treatment of transition metals with macrocyclic nitrogen complexes, [29][30][31][32] Prussian blue analogs 33,34 and ionic liquids [35][36][37] which could be too expensive to be practically utilized.…”

A facile route is described for the synthesis of FeCo alloys encapsulated in the N-doped hierarchical carbon shells (denoted as Fe x Co 100-x @N-doped C) by using a combined hydrothermal carbonization of cellulose and NH 3 microwave ammoxidation. Various spectroscopic measurements are used to characterize the physicochemical properties of Fe x Co 100-x @N-doped C samples and their activity as well as stability in the oxygen reduction reaction (ORR) are investigated in alkaline electrolytes. The Fe x Co 100-x @N-doped C samples exhibit the core FeCo bimetals alloying with N (verified by X-ray absorption spectroscopy [XAS] and transmission electron microscopy) and N-doped onto highly porous carbons in the shell (proofed by N 2 adsorption-desorption isotherms and X-ray photoelectron spectroscopy [XPS]). Among the Fe x Co 100-x @N-doped C catalysts, the Fe 50 Co 50 @N-doped C with an atomic alloy ratio of FeCo (1:1) has a higher ORR performance (E onset = −0.05 V vs Ag/AgCl) and a surpassing durability (via a 4-electron ORR route) in comparison to other Fe x Co 100-x @N-doped C and commercial Pt/C catalysts. By XAS and XPS, the formation of Fe-N in the inner core and pyridinic-N on outer shell may be responsible for the superior ORR performance of Fe 50 Co 50 @Ndoped C catalysts. These biomass-derived carbon composites with unique coreshell FeCoN@N-doped porous carbon structure prepared by using a time and energy saving microwave-assisted method could offer a possible cathodic electrode in fuel cell applications.

Nanomaterials derived from Prussian blue (PB) and its analogues (PBAs) possess uniform active centers and large surface areas, which can be applied in the field of electrocatalysis. In this study, nickel‐iron‐cobalt trimetallic PBAs, that is, NiFeCo(4 : 1)PBA nanocubes, were grown in situ on nickel foam (NF), which was subsequently calcined in air to obtain a composite electrode, NiO/FeOX/Co3O4@NF, with a loose porous hollow nanocube morphology. This structure remarkably enlarged the contact area between the electrolyte and the catalyst. In addition, a synergistic effect among these metallic oxides expedited oxygen evolution reaction (OER) kinetics. The Tafel slope (71.25 mV dec−1) toward OER of the constructed electrode is fairly small, much lower than that of our prepared bimetallic oxides@NF electrodes. The enduring stability is more than 22 h. This work indicates that, through morphology and composition control, the electrocatalytic performance of the designed electrode can be effectively improved.
