“…It is our opinion that a systematic and consistent study of the OER at the oxidised surfaces of electrodes of adjacent first row transition metals should prove useful in elucidating whether a common reaction mechanism prevails, and if so, which (if any) of the previously proposed pathways is most likely. Polycrystalline nickel anodes have been commercially utilised in water electrolysis and consequently there exists a significant body of work on this system [24][25][26][27][28][29][30][31][32]. In contrast, we are aware of only three separate studies [33][34][35][36] on the OER at oxidised cobalt electrodes, while our own work [37,38] is, to the best of our knowledge, the only published account of the reaction at oxidised iron anodes.…”

“…[56][57][58][59][60][61][62][63][64] In addition, β-Ni(OH) 2 and β-NiOOH were regarded as superior catalysts compared with α-Ni(OH) 2 and γ-NiOOH because the catalytic efficiency was enhanced upon its transformation from α-Ni(OH) 2 into β-Ni(OH) 2 after electrochemical aging treatment in KOH electrolyte. [54,55] However, Corrigan claimed that the improvement of the catalytic activity after the treatment was not due to phase transformation but due to the incorporation of Fe impurities.…”

fossil fuels are being widely researched for the development of a sustainable energy system. Among the various candidates for green energy resources, hydrogen energy has been at the center of attention. [1,2] Hydrogen is both inexhaustible and environmentally friendly, because it can be produced from earth-abundant reactants such as water and methane and because no CO 2 or other toxic products are emitted during its conversion into other energy form such as electricity, respectively. Moreover, hydrogen can exhibit significantly larger energy density compared with other energy sources such as gasoline and coal. The most widely used method of hydrogen production today is steam reforming because of its low cost in the process. [3] Nevertheless, the release of carbon monoxide or carbon dioxide as byproducts in the steam reforming process diminishes the environmental merits of hydrogen energy. Thus, as a possible cleaner alternative, an electrolysis method that involves producing hydrogen by electrochemically splitting water has been extensively investigated. Using one of the most abundant resources, water, the production of hydrogen from it yields only oxygen as a byproduct.In the water electrolysis, the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) occur simultaneously, as described by the following equationsIn order for the reaction to proceed, a voltage of 1.23 V is theoretically required between an anode and a cathode. However, an overpotential (represented by the symbol η) should be additionally applied to account for the potential loss resulting from kinetic limitations occurring during the electrochemical reaction. The use of electrocatalysts can lower the overpotential by kinetically facilitating the water-splitting reaction either in HER or OER. Due to the nature of four-electron involving OER, it is generally believed that the OER is much more sluggish than the HER; thus, the development of efficient OER Hydrogen is a promising alternative fuel for efficient energy production and storage, with water splitting considered one of the most clean, environmentally friendly, and sustainable approaches to generate hydrogen. However, to meet industrial demands with electrolysis-generated hydrogen, the development of a low-cost and efficient catalyst for the oxygen evolution reaction (OER) is critical, while conventional catalysts are mostly based on precious metals. Many studies have thus focused on exploring new efficient nonprecious-metal catalytic systems and improving the understandings on the OER mechanism, resulting in the design of catalysts with superior activity compared with that of conventional catalysts. In particular, the use of multimetal rather than single-metal catalysts is demonstrated to yield remarkable performance improvement, as the metal composition in these catalysts can be tailored to modify the intrinsic properties affecting the OER. Herein, recent progress and accomplishments of multimetal catalytic systems, including several important groups of catalysts: layered h...

“…This high charging voltage may be due to the poor catalytic activity of the platinum/platinum black electrode for the OER at room temperature in the aqueous solution of saturated LiOH with 10 M LiCl. Metal electrodes such as Ag and Ni, which exhibit excellent catalytic activity for the OER in alkaline solution [70,71], were unstable in the (15-30 μm), and the catalytic activities of these electrodes were compared using linear sweep voltammetry [68]. The highest catalytic activity for the OER was observed for RuO 2 in an aqueous solution of saturated LiOH with 10 M LiCl.…”
