Abstract Metal–nitrogen–carbon (M–N–C) materials have attracted much interest in bifunctional oxygen‐involving electrocatalysis for rechargeable Zn–air batteries. Such M–N–C electrocatalysts with M–N x sites show good activity the oxygen reduction reaction (ORR) but moderate evolution (OER). Herein, an oxygen‐rich material (O–Co–N/C) a highly porous nanosheet structure is reported as electrocatalyst, which prepared by direct pyrolysis of ultrathin CoO nanosheets decorated zeolitic imidazolate framework‐8 nanoparticles under inert atmosphere. Particularly, Co O–Co–N/C electrocatalyst contain both Co–N and Co–O coordination environments to provide intrinsic active ORR OER, respectively. Furthermore, electrochemical studies that catalyst retains comparable common half‐wave potential 0.85 V vs reversible hydrogen electrode better OER overpotential 0.29 at current density 10 mA cm −2 . This study provides insights into development effective metal centers coordinated nitrogen atoms.

Abstract The development of highly efficient and robust bifunctional electrocatalysts for oxygen reduction (ORR) evolution reactions (OER) is the key issue realizing high‐performance long‐life rechargeable zinc–air batteries (ZABs). However, it still a great challenge to integrate independent ORR OER sites in catalyst with high activity. Here, carbon nanotube‐bridging strategy proposed synthesize such electrocatalyst enriched active single‐atom Fe nanosized NiCo hydroxides OER. Consequently, developed shows small overpotential difference 0.686 V. When used as an electrode catalyst, corresponding ZAB exhibits large power density 219.5 mW cm −2 , charge–discharge voltage gap 0.72 V at 10 mA outstanding discharge–charge durability without attenuation after more than 700 cycles. This work proposes new idea realize multifunctional catalysts drives practical application ZABs.

Abstract Hydrogen energy is regarded as the ultimate source for future human society, and preparation of hydrogen from water electrolysis recognized most ideal way. One key factors to achieve large‐scale production by splitting availability highly active stable electrocatalysts. Although non‐precious metal electrocatalysts have made great strides in recent years, best evolution reaction (HER) are still based on noble metals. Therefore, it particularly important improve overall activity while reducing metals load. Alloying strategies can shoulder burden optimizing cost improving performance. With this mind, work application metal‐based alloy field summarized. In review, first, mechanism HER described; then, current development synthesis methods presented; finally, an example analysis practical studies presented. addition, at end prospects, opportunities, challenges facing tried discuss.
