“…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.

“…However, the heteroatom doping occasionally causes the conductivity decline of the material. In order to further improve the activity of the metal single atoms catalyst, by combining metal, metal cluster, metal carbide, metal nitride, metal oxides with support, the coordination ability of the MM bond can effectively suppress the aggregation of metal atoms …”

Nonprecious metal single‐atom materials have attracted extensive attention in the field of electrocatalysis due to their low cost, high reactivity, high selectivity, and high atomic utilization. However, the high surface energy of a single atom causes agglomeration during preparation and catalytic measurement, resulting in damage to the catalytic sites. The strong interaction between substrate and monoatoms is the key factor to prevent the aggregation of individual metal atoms, and the geometry and electronic structure of the catalysts can be adjusted to optimize the catalytic activity. Due to the hierarchically pores, high specific surface area, and defect effect, nitrogen‐doped porous carbon (NPC) has been widely studied as an ideal nonprecious metal single‐atom support, which synergistically enhance the electrocatalytic performance toward oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, carbon dioxide reduction reaction, and nitrogen reduction reaction with non‐noble metal single atoms. This review summarizes the controllable synthesis, characterization, theoretical calculation, and application of M (M = Co, Fe, Ni, Cu, Zn, Mo, etc.) single atoms on nitrogen‐doped porous carbon. Finally, the future development and challenges of nitrogen‐doped porous carbon supported nonprecious metal single‐atom electrocatalysts for practical commercialization are concluded.

“…[124] The commonly used method for preparing Co SAs starts from the Co-based salts with carbon materials. [125][126][127][128] For instance, very small amounts of Co dispersed as individual atoms on N-doped graphene (NG) sheets were reported to serve as extraordinary catalysts for the HER. [125] The excellent catalytic performance, maximal efficiency of atomic utilization, scalability, and low-cost make this catalyst a promising candidate to replace noble metal Pt in water-splitting applications.…”

Energy conversion and storage applications require highly stable and efficient electrocatalysts/electrodes to facilitate electrochemical reactions, but these materials commonly suffer from serious atom wastes and lower performances than the theoretical levels, which cannot meet the increasing demands of the green atomic economy, thereby limiting their practical applications. Recently, metal single atoms (SAs) have attracted tremendous attention owing to their merits of full atom utilization, unique electronic structures, tunable surface characteristics, and low costs. However, metal SAs usually have relatively low physical/chemical stabilities due to their high surface energy, which results in severe degradation of electrochemical performances. Novel synthetic strategies are developed for metal SAs with better stability and performance. In this review, these strategies will be introduced in the context of electrocatalysis and batteries. Specifically, the design concepts, synthesis approach properties, and applications of metal SAs will be discussed. Finally, the critical challenges and future perspectives of metal SAs are presented. This review aims to provide new insights for future work as well as the real-world applications of metal SAs.
