“…Moreover, single Fe atoms can also significantly increase the CO 2 RR activity ( Figure 5C ). Tang et al reported an atomically dispersed Fe-coordinated N-doped carbon catalyst that enhanced CO 2 reduction to produce CO with high activity ( Takele Menisa et al, 2022 ). The neighboring graphitic N transferred more electrons to the intermediate COOH*, increasing COOH* adsorption strength.…”

Excess of carbon dioxide (CO2) in the atmosphere poses a significant threat to the global climate. Therefore, the electrocatalytic carbon dioxide reduction reaction (CO2RR) is important to reduce the burden on the environment and provide possibilities for developing new energy sources. However, highly active and selective catalysts are needed to effectively catalyze product synthesis with high adhesion value. Single-atom catalysts (SACs) and double-atom catalysts (DACs) have attracted much attention in the field of electrocatalysis due to their high activity, strong selectivity, and high atomic utilization. This review summarized the research progress of electrocatalytic CO2RR related to different types of SACs and DACs. The emphasis was laid on the catalytic reaction mechanism of SACs and DACs using the theoretical calculation method. Furthermore, the influences of solvation and electrode potential were studied to simulate the real electrochemical environment to bridge the gap between experiments and computations. Finally, the current challenges and future development prospects were summarized and prospected for CO2RR to lay the foundation for the theoretical research of SACs and DACs in other aspects.

“…The findings of Zhang et al were confirmed by the works of Zhu et al 227 The latter also observed that graphitic N further improved the catalytic performance of Fe–N 4 sites by lowering the free energy of the formation of the *COOH intermediate. Takele Menisa et al 223 also attribute the efficient electrochemical CO 2 reduction of FeN 4 C to the presence of the neighboring graphitic nitrogen. The group reports that the increase in the number of neighboring graphitic nitrogen decreases the number of electrons transferred between *CO and the catalyst, which reduces the energetic barrier for the desorption of *CO.…”

The electrochemical reduction of carbon dioxide offers a sound and economically viable technology for the electrification and decarbonization of the chemical and fuel industries. In this technology, an electrocatalytic material and renewable energy‐generated electricity drive the conversion of carbon dioxide into high‐value chemicals and carbon‐neutral fuels. Over the past few years, single‐atom catalysts have been intensively studied as they could provide near‐unity atom utilization and unique catalytic performance. Single‐atom catalysts have become one of the state‐of‐the‐art catalyst materials for the electrochemical reduction of carbon dioxide into carbon monoxide. However, it remains a challenge for single‐atom catalysts to facilitate the efficient conversion of carbon dioxide into products beyond carbon monoxide. In this review, we summarize and present important findings and critical insights from studies on the electrochemical carbon dioxide reduction reaction into hydrocarbons and oxygenates using single‐atom catalysts. It is hoped that this review gives a thorough recapitulation and analysis of the science behind the catalysis of carbon dioxide into more reduced products through single‐atom catalysts so that it can be a guide for future research and development on catalysts with industry‐ready performance for the electrochemical reduction of carbon dioxide into high‐value chemicals and carbon‐neutral fuels.

“…After this, the research of SAC has been continuously developed. At present, the commonly synthetic methods include the impregnation method, [ 22,23 ] high‐temperature pyrolysis method, [ 24,25 ] atomic layer deposition (ALD) method, [ 26–28 ] coprecipitation method, [ 29,30 ] etc. However, Pt resources are scarce and expensive, which makes it impossible for Pt SACs to achieve large‐scale commercial applications.…”

In recent years, single‐atom catalysts (SACs) have become the most active part of the catalytic field due to their excellent catalytic activity. Among them, Ru SACs exhibit excellent performance in many catalytic applications due to their high atomic utilization efficiency, catalytic activity and selectivity, and relatively low cost. In order to understand the structure–performance relationship and potential catalytic mechanism of Ru SACs, this review summarizes the research progress of Ru SACs in the fields of electrocatalytic water splitting, fuel cells, nitrogen reduction, and nitrate reduction in recent years. The catalytic process of Ru single atom in different synthesis methods and modification strategies is summarized. Finally, some opportunities and challenges for the future development of Ru SACs are prospected.
