“…In order to lower the cost and realize the eco-friendly production, biomass precursors such as natural plants or animals can be excellent candidates without the participation of other nitrogencontaining species. Many biomass materials have been used as precursors to fabricate ORR catalysts with low cost but outstanding activity, reasonable stability and long durability [117][118][119][120]. For example, Liang et al [121] reported a facile and cost-effective strategy to in situ synthesize efficient Fe-N/C catalysts with renewable Auricularia auricular-judae as the biomass precursor (Fig.…”

N, P dual‐doped porous carbon with high specific surface area of ∼2000 m2 g−1 was prepared via foaming‐carbonization process. It was demonstrated that the simple surface treatment and modification can conveniently further improve the catalytic performance of oxygen reduction reaction (ORR). The results showed that chemisorbed phosphorus can promote the surface treatment of sodium borohydride (NaBH4). The modified novel sites, adsorbing water molecules of a semi‐free state, promoted the offensive key steps of H2O molecules in ORR. After post‐treatment, the limit current density increased from 5.0 to 6.1 mA cm−2 with a decreased Tafel slope and the onset potential positively shifted. This surface‐modified catalyst was applied to Zn‐air battery and Al‐air battery, and had exhibited good applicability and excellent performances. This work illustrates that the simple post‐treatments can conveniently and effectively improve the ORR performance of metal‐free carbon catalysts.

“…For PEMFCs and metal-air batteries, the oxygen evolution reaction (OER) at the anode and oxygen reduction reaction (ORR) at the cathode are the main reactions of electrochemical conversion. [14][15][16][17] However, the sluggish kinetics for these two reactions restricts the further application of PEMFCs and metal-air batteries. Therefore, it is particularly important to design catalysts with enhanced activity, high efficiency and high stability.…”

The applications of many energy-related electrochemical energy conversion and storage devices are changing with each passing day. Oxygen evolution reaction (OER), hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR) are the key steps in the commercial application of these energy conversion/storage equipment. Defect-rich transition metal oxides (TMOs), such as Co, Mn, Fe, Ni, etc., have always been one of the most promising electrocatalysts, which are cheap, easy to obtain, high in catalytic activity and stable during electrocatalysis. In this review, we first introduce the definition, classification, characteristics, and construction of defects. Then, the latest developments of defect-rich TMO electrocatalysts in electro-catalysis and energy conversion storage device is summarized. Furthermore, the relationship between defects and activity and the potential mechanism are also discussed. The defects in defect-rich TMOs can adjust the surface/interface electronic structure of the electrocatalyst, change the adsorption energy of the intermediate product, or increase the intrinsic catalytic activity of active sites, which are beneficial for enhanced catalytic performance. Finally, the current challenges and prospects of defect-rich TMO electrocatalysts are proposed. Therefore, the introduction of defects in TMO will be a potential strategy for the rational design of high-performance electrocatalysts in the future.
