Efforts at Enhancing Bifunctional Electrocatalysis and Related Events for Rechargeable Zinc‐Air Batteries

“…Alkaline Electrolytes: Conventional RZAB utilizes aqueous alkaline electrolytes where both the Zn anode and air electrocatalysts are at their best conditions because it endears the following properties: [123][124][125] (i) electrochemical reversibility and fast kinetics of the Zn anode and air electrocatalysts for the ORR and OER; (ii) high ionic conductivity; (iii) relatively good performance at ambient temperature; (iv) high solubility of Zn salts; and (v) possibility of using non-Pt, economically effective and durable positive electrodes. Thus, the most commonly used electrolytes in RZABs are alkaline aqueous solutions containing potassium hydroxide (KOH), [121] sodium hydroxide (NaOH), [126] and lithium hydroxide (LiOH).…”

Rational confinement engineering of MOF‐derived carbon‐based electrocatalysts toward CO2 reduction and O2 reduction reactions

“…[16][17][18][19] Metal organic framework (MOF) is a kind of organicinorganic porous materials composed of organic ligands and metal centers with the crystalline morphology. [20][21][22][23] MOF-derived carbon-based materials have the following advantages: (1) MOF-derived carbon-based materials have high porosity, adjustable pore size, and large specific surface area, which is more conducive to the adsorption of molecules around the reaction substrate, material transport, and activation of the active center. 24,25 (2) Metallic nodes and organic linkers in MOF can catalyze challenging reactions by charge transfer with active centers through coordination or π-π forces, thereby improving the chemical microenvironment of pore structures.…”

Recent advances in the metal–organic framework-based electrocatalysts for the hydrogen evolution reaction in water splitting: a review

“…However, as precursors, MOFs can produce a variety of metal compounds or metal and carbon composites with deliberate consideration of the elemental structures and compositions. 15 Taking advantage of the high surface area and porosity of the MOFs, it has been employed as a catalyst for HER in the last few decades. 16 In addition, it has been used as an electrocatalyst for HER because of the following reasons: (i) to replace the expensive metal-based catalysts (PGM) with low-cost metals, (ii) for lowering the needed overpotential during HER, (iii) for escalating the kinetics of the reaction.…”
