“…Similarly, the introduction of oxygen vacancies into the crystals of ABO 3 perovskite oxides is also used to improve the catalytic activity. [98][99][100] Encapsulation of TM compounds including alloys, hydroxides, sulfides, phosphates and nitrides nanoparticles in N-doped carbon is also an effective method to generate materials rich in electrocatalytic active sites. [68,[101][102][103][104][105][106][107][108] The N-doped carbon effectively facilitates the electron transport and prevents the aggregation of nanoparticles.…”

Rechargeable zinc-air batteries (ZABs) are considered as one of the most promising electrochemical energy devices due to their various unique advantages. Oxygen electrocatalysis, involving the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), determines the overall performance of zinc-air batteries. Therefore, the development of highly efficient bifunctional ORR/OER catalysts is critical for the large-scale application of ZABs. Carbonbased nanomaterials have been widely reported to be efficient electrocatalysts toward both ORR and OER. The enhanced activity of these electrocatalysts are usually attributed to different doping defects, synergistic effects and even the intrinsic carbon defects. Herein, an overview of the defect engineering in carbon-based electrocatalysts for ORR and OER is provided. The different types of intrinsic carbon defects and strategies for the generation of other defects in carbon-based electrocatalysts are presented. The interaction of heteroatoms doped carbon and transition metals (TMs) is also explored. In the end, the existing challenges and future perspectives on defect engineering are discussed.

The development of cost‐effective efficient bifunctional electrocatalysts for metal‐air batteries is an important aspect for its commercialization. We demonstrate the effect of Co nanoparticles and/or the porous carbon matrix in pristine CoFe2O4 (CFO) electrocatalysts towards the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). The Co/CoFe2O4‐carbon network (CCFOC) with a high surface area and good conductivity offered more active sites for oxygen adsorption as well as accelerated electron transfer kinetics, leading to superior ORR and OER activities. A Li‐air battery split cell was fabricated using the CCFOC as an air‐breathing electrode, which exhibited a high discharge capacity of 4320 mAh g−1 at a high current density of 100 mA g−1 with an acceptable cycling stability and columbic efficiency. The fabricated coin cell or the split cell Li‐air battery could power a commercial 2.8 V green LED bulb continuously for more than 6 h.

“…[13] The OER involves four steps, with one electron coupled per step, while the HER is a two electron-transfer reaction; consequently, the OER generally exhibits sluggish kinetics and requires a larger overpotential than the HER. [14][15][16][17] Hence, OER electrocatalyst design plays a key role in efficient water splitting. The proposed reaction mechanism for the OER under basic conditions is summarized as follows…”

are required. [2a,b,3] Among the various sustainable energy candidates, hydrogen fuel has garnered significant attention owing to its natural advantages. Hydrogen is typically a nontoxic and environmentally friendly power source that can be produced from water, which is an earth-abundant reactant, and produces no CO 2 emissions when converted into other energy forms. [4-6] In addition, due to its high mass-specific energy density, hydrogen can be efficiently used in mobile applications. Moreover, hydrogen can be used in combustion engines and fuel cells. Hence, the development of efficient hydrogen-based energy systems is necessary. [7-9] Producing hydrogen by electrolytic water splitting is considered a promising approach to resolve the current environmental crisis and has been extensively investigated with emphasis on availability and sustainability. [10,11] During water electrolysis, the cathodic hydrogen evolution reaction (HER) [12] and the anodic oxygen evolution reaction (OER) occur simultaneously, as exemplified by the following equations
