“…However, the electrocatalytic OER performances of the NiO nanostructures are still unsatisfiable because of their sluggish kinetics, low electronic conductivity, and limited active sites [ 32 , 33 ]. To release such drawbacks, thus, anchoring of NiO with carbonaceous materials (e.g., carbon particles [ 32 ], carbon nanotubes [ 33 , 34 ], carbon fibers [ 35 ], carbon nanowires [ 36 ], activated carbon (AC) [ 37 ], graphene [ 38 , 39 , 40 ], reduced graphene oxide [ 41 , 42 ], etc.) has been proposed as an effective way to improve the electrical conductivity as well as the vigorous kinetic reaction.…”

“…Furthermore, due to its environmental friendliness, vast abundance, fast regeneration, and low cost, biomass-derived AC has attracted extensive attention from the next-generation energy technology community [ 43 , 44 , 45 , 46 , 47 ]. However, most of all previous works have still used some chemical solutions (e.g., solvents and/or acids) for the formation of both electrocatalysts and carbonaceous materials [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ]. Therefore, developing an ecofriendly and chemical-free synthesis method is essential to realize the fully green energy technology.…”

A sustainable and efficient electrocatalyst for the oxygen evolution reaction (OER) is vital to realize green and clean hydrogen production technology. Herein, we synthesized the nanocomposites of activated carbon-anchored nickel oxide (AC-NiO) via fully green routes, and characterized their excellent OER performances. The AC-NiO nanocomposites were prepared by the facile sonication method using sonochemically prepared NiO nanoparticles and biomass-derived AC nanosponges. The nanocomposites exhibited an aggregated structure of the AC-NiO nanotablets with an average size of 40 nm. When using the nanotablets as an OER catalyst in 1 M KOH, the sample displayed superb electrocatalytic performances, i.e., a substantially low value of overpotential (320 mV at 10 mA/cm2), a significantly small Tafel slope (49 mV/dec), and a good OER stability (4% decrease of overpotential after 10 h). These outstanding OER characteristics are considered as attributing to the synergetic effects from both the ample surface area of the electrochemically active NiO nanoparticles and the high electrical conductivity of the AC nanosponges. The results pronounce that the fully ecofriendly synthesized AC-NiO nanotablets can play a splendid role as high-performance electrocatalysts for future green energy technology.

Oxygen evolution reaction (OER) suffers from four-electron transfer, sluggish kinetics and high energy requirements, limiting the development of new energy technologies such as hydrogen production from water electrolysis. In recent years, non-noble metal composite catalysts have attracted increasing attention due to their advantages of excellent catalytic activity and cost compared with noble metal-based catalysts. This review summarizes the latest progress in this field. Firstly, the OER mechanism and the evaluation methods of catalytic performance are briefly introduced. Then the non-noble metal/nitrogen-doped carbon composites are further classified into metal/nitrogen-doped carbon composites, metal single atom/nitrogen-doped carbon composites, alloy/nitrogen-doped carbon composites, and metal oxide/nitrogen-doped carbon composites. The research progress of the electrocatalysts is summarized and analyzed based on the synthesis method and catalytic activity, aiming to explore the role of nitrogen-doped carbon materials in catalyst structure and catalyst performance. Finally, perspectives are given out for the current problems and future directions of non-noble metal/nitrogen-doped carbon composites.

“…Therefore, most of the nickel oxides‐based OER catalysts are either prepared in composite or heavily modified in both shape and intrinsic properties. By means of making an OER electrocatalyst using nickel oxide, Xie et al 73 used Ni@NiO/N‐C nanowires synthesized from Ni‐based MOF with a core‐shell structure. By a series of pyrolysis and oxidation, the produced Ni@NiO/N‐C exhibited 390 mV of overpotential to reach the current density of 10 mA/cm 2 and a Tafel slope of 100 mV/dec.…”

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.
