“…As a result, single-atom catalysis has been proven to be a powerful and effective solution in many typical heterogeneous catalytic reactions, including electrochemical reactions, water-gas shift reactions, hydrogenation reactions, etc. [211][212][213][214][215][216][217] and in particular, SACs obtained through scalable synthesis methods have potential industrial applications. In addition, SACs have established a bridge to link homogeneous and heterogeneous catalysis by providing single active sites on solid surfaces.…”

Single-atom catalysis is a powerful and attractive technique with exceptional performance, drastic cost reduction and notable catalytic activity and selectivity. In single-atom catalysis, supported single-atom catalysts contain isolated individual atoms dispersed on, and/or coordinated with, surface atoms of appropriate supports, which not only maximize the atomic efficiency of metals, but also provide an alternative strategy to tune the activity and selectivity of catalytic reactions. This review will highlight the attributes of single-atom catalysis and summarize the most recent advancements in single-atom catalysts with a focus on the design of highly active and stable single atoms. In addition, new research directions and future trends will also be discussed.

Summary A series of NiSFeS/N, S co‐doped carbon (NixFeyS/NSC) for electrochemical oxygen evolution reaction (OER) were synthesized by a co‐precipitation method and followed by pyrolysis in N2 atmosphere. NiSFeS hybrid was uniformly integrated with N, S co‐doped carbon in NixFeyS/NSC. NixFeyS/NSC showed high OER catalytic activity, and the optimized Ni60Fe40S/NSC afforded an OER overpotential of ~239 mV to deliver a current density of 10 mA cm−2 and showed a corresponding Tafel slope of ~30.9 mV dec−1 in 1 M KOH. Such OER catalytic activity was not only higher than that of IrO2, but also comparable with that of the most recently reported NiFe‐based sulfides for OER. Further study indicated that hybridizing NiS with FeS resulted in a synergistic effect for OER. The hybridization increased total amount of sulfides as active species, therefore enhancing the OER catalytic activity. In addition, the hybridization benefited the formation of petal‐like morphologies that contributing much to higher electrochemically active surface area (ECSA), and also boosted the content of graphitic and N, S co‐doped carbon that improving charge transfer efficiency.

Efficient yet low-cost electrocatalysts for the oxygen reduction reaction (ORR) are highly desirable for energy systems such as metal-air batteries and fuel cells. Herein, we report the synthesis of efficient cobalt-modified nitrogen-doped carbon (NÀ C/Co) electrocatalysts by using a one-pot pyrolysis. The abundant source of N in g-C 3 N 4 contributes to the in situ N doping in the carbon matrix, which favors the formation of Co-related catalytic active sites. The NÀ C/Co-1 (prepared with 1 mmol Co salt) sample exhibits the best performance towards the ORR, with a positive half-wave potential of 0.86 V (vs. the reversible hydrogen electrode, RHE), high stability and excellent methanol tolerance, which outperforms the commercial Pt/C catalyst. We find that the high performance is dependent on the optimal content of Co that can achieve the maximum amount of CoÀ N x catalytic species. In addition, we reveal that the size effect of Co nanoparticles is not the determining factor for the ORR activity in the current system, as the kinetics of the ORR reaction is dominantly determined by the active sites derived from CoÀ N x species. By exploiting the NÀ C/Co-1 sample as an air cathode catalyst, the assembled Zn-air battery presents a maximal power density of 153 mW cm À 2 as well as good durability during continuous cycle tests.
