“…In contrast to N, B possesses lower electronegativity (~ 2.04) than C (~ 2.55) [54], and if doped to carbon, B becomes an electron acceptor, inducing a positive charge and resulting in charged sites (B + ) that favor O 2 adsorption and thus increased ORR activity [55,56]. To study the important effects of B-doping and to create sufficient active sites, researchers [54,57,58] have focused their attention on combining mesoporous carbon structures with B-doping to explore advanced metal-free carbon catalysts. For example, Shu et al [57] prepared novel mesoporous boron-doped onion-like carbon (B-OLC) microspheres using nanodiamond and boric acid as C and B sources for rechargeable sodium-oxygen (Na-O 2 ) batteries.…”

“…To obtain optimal bifunctional catalysts, an important comparison of the different types of heteroatom-doping was conducted by Su et al [58], in which N, B, and P were used to dope ordered mesoporous carbons (OMCs). The researchers found that improvements to charge transfer kinetics is strongly depended on the nature of the doped heteroatom.…”

Metal-air batteries (MABs), particularly rechargeable MABs, have gained renewed interests as a potential energy storage/conversion solution due to their high specific energy, low cost, and safety. The development of MABs has, however, been considerably hampered by its relatively low rate capability and its lack of efficient and stable air catalysts in which the former stems mainly from the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) and the latter stems from the corrosion/oxidation of carbon materials in the presence of oxygen and high electrode potentials. In this review, various carbon-composited bifunctional electrocatalysts are reviewed to summarize progresses in the enhancement of ORR/OER and durability induced by the synergistic effects between carbon and other component(s). Catalyst mechanisms of the reaction processes and associated performance enhancements as well as technical challenges hindering commercialization are also analyzed. To facilitate further research and development, several research directions for overcoming these challenges are also proposed.

“…Su et al. reported a facile approach for the synthesis of a series of boron‐doped ordered mesoporous carbon with different B content . The B doping significantly enhances the ORR activity in alkaline media; in particular, a carbon material with 1.17 wt % B dopant showed an optimum ORR activity.…”

Metal‐air batteries (MABs) and reversible fuel cells (RFCs) rely on the bifunctional oxygen catalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Finding efficient bifunctional oxygen catalysts is the ultimate goal and it has attracted a great deal of attention. The dilemma is that a good ORR catalyst is not necessarily efficient for OER, and vice versa. Thus, the development of a new type of bifunctional oxygen catalysts should ensure that the catalysts exhibit high activity for both OER and ORR. Composites with multicomponents for active centers supported on highly conductive matrices could be able to meet the challenges and offering new opportunities. In this Review, the evolution of bifunctional catalysts is summarized and discussed aiming to deliver high‐performance bifunctional catalysts with low overpotentials.

“… 20 For example, adding nitrogen dopants that have higher electronegativity will generate positive charge density on carbon atoms and the O 2 chemisorption will change, which in turn will also effectively weaken the O–O bond and thereby promote the ORR. 21 Most commonly used heteroatoms for carbon doping are nitrogen, 20 , 22 boron, 23 , 24 sulfur, 25 , 26 and phosphorus. 27 , 28 Special focus has lately been directed to nitrogen-doped carbon as ORR catalysts, as interest in this topic has grown considerably.…”

In this recent decade, great interest has risen to develop metal-free and cheap, biomass-derived electrocatalysts for oxygen reduction reaction (ORR). Herein, we report a facile strategy to synthesize an electrochemically active nanocarbon material from the renewable and biological resource, wood biomass. The ORR activity of the catalyst material was investigated in 0.1 M KOH solution by employing the rotating disc electrode method. Scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy were employed to obtain more information about the catalyst material’s morphology and composition. The material exhibits outstanding electrocatalytic activity with low onset potential and high current density, similar to that of a commercial Pt/C catalyst in an alkaline medium. The results clearly ascertain that wooden biomass can be easily transformed into novel carbon nanostructures with superior ORR activity and possibility to be used in fuel cells and metal–air batteries.
