“…Except for PBA precursors, other nitrogen containing MOFs such as Zn or Co‐based zeolitic imidazolate framework (ZIF‐8, ZIF‐67) could also be potential template for synthesizing M@NG with a small amount of precious metal. [ 56‐59 ]…”

Despite progress over the past few years in developing efficient low‐cost catalysts, precious metals are still the best catalysts for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). However, the natural scarcity and high cost greatly hamper their large‐scale commercialization. The combination of graphene shell with metal core could tune the electronic structure of carbon active sites. Recently, nitrogen doped graphene encapsulated metal or alloy (M@NG) has emerged as novel and fascinating electrocatalysts. In this review, we focus on some recent advances in designing M@NG electrocatalysts for HER, OER and ORR through tuning electronic structure and activity of carbon active sites. We have summarized some facile and universal strategy for synthesizing various M@NG via direct annealing of metal‐organic frameworks (MOFs). With elaborated MOFs precursor design, careful control over the nitrogen doping level, metal element types and alloy structure, the electronic structure of carbon active sites can be rationally tuned to optimize activity for different electrochemical reactions. We hope this review can provide new insights into the design of M@NG with high catalytic activity.

“…2(a)–(f) shows the regular dodecahedron geometry observed in the ZIF-8 and NZ-X samples, consistent with the structure described in the literature. 33 Therefore, it can be observed that the shape of NZ-X is still a regular dodecahedron with the increase of the Ni doping amount, thus retaining the excellent properties of ZIF-8, which is beneficial to its gas adsorption performance. Furthermore, as the Ni doping amount increased, the particle size of NZ-X decreased, while the structure was slightly agglomerated by adhesion.…”

Metal–organic frameworks are considered ideal precursors for the preparation of transition-metal, heteroatom-doped carbon catalysts that are perceived to be efficient electrocatalysts for energy storage devices. Herein, we demonstrate the synthesis of ZIF-67-derived Co-incorporated N-doped porous carbon catalysts supported on high surface area microporous carbon prepared from a lotus seed shell. The combination of the two carbon catalysts in different weight ratios resulted in Co-incorporated N-doped carbon sheets with tuned surface area and porosity, enabling enhanced oxygen reduction reaction (ORR) activity in an alkaline medium. The optimized carbon catalyst ZL 600 (3:1) exhibited a half-wave potential of 0.79 V vs RHE and a limiting current density of −4.38 mA cm–2 in 0.1 M KOH solution with higher stability and methanol tolerance. The optimized sample ZL 600 (3:1) demonstrated as a cathode in a zinc–air battery exhibited an open circuit voltage of 1.29 V with a flat discharge profile at a current rate of 10 mA cm–2. The homemade system produced a specific capacity of 610 mAh g–1 and a peak power density of 111 mW cm–2, comparable to the cathode made with Pt/C. The high micro-mesoporosity, pyridinic and pyrrolic nitrogen contents, as well as enriched Co-active centers protected by carbon sheets favorably contributed to the efficient ORR mechanism.
