Steps to balance: Step 1: Separate the half-reactions that undergo oxidation and reduction. Oxidation: I − I 2. This is the oxidation half because the oxidation state changes from -1 on the left side to 0 on the right side. This indicates a gain in electrons. Reduction: MnO − 4 Mn2 +. Step 3: Verify that the equation is balanced. Since there are an equal number of atoms of each element on both sides, the equation is balanced. 2 C 2 H 2 + 5 O 2 = 4 CO 2 + 2 H 2 O.

However, large-scale H2 production is greatly hindered by the sluggish oxygen evolution reaction (OER) kinetics at the anode of a water electrolyzer. Although many OER electrocatalysts have been developed to negotiate this difficult reaction, substantial progresses in the design of cheap, robust, and efficient catalysts are still required and have been considered a huge challenge. Herein, we report the simple synthesis and use of α-Ni(OH)2 nanocrystals as a remarkably active and stable OER catalyst in alkaline media. We found the highly nanostructured α-Ni(OH)2 catalyst afforded a current density of 10 mA cm(-2) at a small overpotential of a mere V and a small Tafel slope of ~42 mV/decade, comparing favorably with the state-of-the-art RuO2 catalyst. This α-Ni(OH)2 catalyst also presents outstanding durability under harsh OER cycling conditions, and its stability is much better than that of RuO2. Additionally, by comparing the performance of α-Ni(OH)2 with two kinds of β-Ni(OH)2, all synthesized in the same system, we experimentally demonstrate that α-Ni(OH)2 effects more efficient OER catalysis. These results suggest the possibility for the development of effective and robust OER electrocatalysts by using cheap and easily prepared α-Ni(OH)2 to replace the expensive commercial catalysts such as RuO2 or IrO2....read moreAbstract: Ni-(oxy)hydroxide-based materials are promising earth-abundant catalysts for electrochemical water oxidation in basic media. Recent findings demonstrate that incorporation of trace Fe impurities from commonly used KOH electrolytes significantly improves oxygen evolution reaction (OER) activity over NiOOH electrocatalysts. Because nearly all previous studies detailing structural differences between α-Ni(OH)2/γ-NiOOH and β-Ni(OH)2/β-NiOOH were completed in unpurified electrolytes, it is unclear whether these structural changes are unique to the aging phase transition in the Ni-(oxy)hydroxide matrix or if they arise fully or in part from inadvertent Fe incorporation. Here, we report an investigation of the effects of Fe incorporation on structure–activity relationships in Ni-(oxy)hydroxide. Electrochemical, in situ Raman, X-ray photoelectron spectroscopy, and electrochemical quartz crystal microbalance measurements were employed to investigate Ni(OH)2 thin films aged in Fe-free and unpurified (reagent-grade)......read moreAbstract: Prussian blue, which typically has a three-dimensional network of zeolitic feature, draw much attention in recent years. Besides their applications in electrochemical sensors and electrocatalysis, photocatalysis, and electrochromism, Prussian blue and its derivatives are receiving increasing research interest in the field of electrochemical energy storage due to their simple synthetic procedure, high theoretical specific capacity, non-toxic nature as well as low price. In this review, we give a general summary and evaluation of the recent advances in the study of Prussian blue and its derivatives for batteries and supercapacitors, including synthesis, micro/nano-structures and electrochemical properties....read moreAbstract: Oxygen evolution reaction (OER) is an essential electrochemical reaction in water-splitting and rechargeable-metal-air-batteries to achieve clean energy production and efficient energy-storage. At first, this review discusses about the mechanism for OER, where an oxygen molecule is produced with the involvement of four electrons and OER intermediates but the reaction pathway is influenced by the pH. Then, this review summarizes the brief discussion on theoretical calculations, and those suggest the suitability of NiFe based catalysts for achieving optimal adsorption for OER intermediates by tuning the electronic structure to enhance the OER activity. Later, we review the recent advancement in terms of synthetic methodologies, chemical properties, density functional theory (DFT) calculations, and catalytic performances of several nanostructured NiFe-based OER electrocatalysts, and those include layered double hydroxide (LDH), cation/anion/formamide intercalated LDH, teranary LDH/LTH (LTH: Layered-triple-hydroxide), LDH with defects/vacancies, LDH integrated with carbon, hetero atom doped/core-shell structured/heterostructured LDH, oxide/(oxy)hydroxide, alloy/mineral/boride, phosphide/phosphate, chalcogenide (sulfide and selenide), nitride, graphene/graphite/carbon-nano-tube containing NiFe based electrocatalysts, NiFe based carbonaceous materials, and NiFe-metal-organic-framework (MOF) based electrocatalysts. Finally, this review summarizes the various promising strategies to enhance the OER performance of electrocatalysts, and those include the electrocatalysts to achieve ~1000 mA cm−2 at relatively low overpotential with significantly high stability....read moreAbstract: The active site for electrocatalytic water oxidation on the highly active iron(Fe)-doped β-nickel oxyhydroxide (β-NiOOH) electrocatalyst is hotly debated. Here we characterize the oxygen evolution reaction (OER) activity of an unexplored facet of this material with first-principles quantum mechanics. We show that molecular-like 4-fold-lattice-oxygen-coordinated metal sites on the (1211) surface may very well be the key active sites in the electrocatalysis. The predicted OER overpotential (ηOER) for a Fe-centered pathway is reduced by V relative to a Ni-centered one, consistent with experiments. We further predict unprecedented, near-quantitative lower bounds for the ηOER, of and V for pure and Fe-doped β-NiOOH(1211), respectively. Our hybrid density functional theory calculations favor a heretofore unpredicted pathway involving an iron(IV)-oxo species, Fe4+=O. We posit that an iron(IV)-oxo intermediate that stably forms under a low-coordination environment and the favorable discharge of......read more
