“…In M-N-C materials, when the central metal atom is transition metal element, the nitrogen coordination number can be more than four, [144,145] and the four nitrogen coordination is not always favorable to CO 2 RR. [146][147][148][149] Other nitrogen coordination numbers, such as M-N 2 , [150] M-N 3 , [151] and M-N 5 , [12] have good catalytic effect on CO 2 RR.…”

Electrochemical carbon dioxide reduction reaction (CO2RR) is an efficient strategy to relieve global environmental and energy issues by converting excess CO2 from the atmosphere to value‐added products. Atomically dispersed metal‐nitrogen‐doped carbon (M‐N‐C) materials are superior catalysts for electrocatalytic CO2RR because of the 100% atomic utilization, unsaturated coordination configuration, relatively uniform active sites, and well‐defined and adjustable structure of active centers. However, the electrochemical CO2RR is a great challenge due to the process involving proton‐coupled multi‐electron transfer with a high energy barrier, which leads to unsatisfactory selectivity to the targeted product, especially for C2 products (e.g., C2H4 and C2H5OH). Here, the authors systematically summarize effective means, including reasonable selection of isolated metal sites, regulation of the coordination environment of isolated metal atoms, and fabrication of dimetallic single‐atom sites for attaining optimal geometric and electronic structures of M‐N‐C materials and further correlate these structures with catalytic selectivity to various C1 (e.g., CO and CH4) and C2 products in the CO2RR. Moreover, constructive strategies to further optimize M‐N‐C materials for electrocatalytic CO2RR are provided. Finally, the challenges and future research directions of the application of M‐N‐C materials for electrocatalytic CO2RR are proposed.

“…By this method, the film thickness can be controlled by increasing the number of cycles. [57] Advances in MOFs and COFs provide a unique opportunity to molecularly disperse catalytic centres using reticular chemistry. [58] To prepare MOF-and COF-based MDAs, the molecular complexes should possess more than two functionalities to be extended in the framework structure.…”

Global climate changes have been impacted by the excessive CO 2 emission, which exacerbates the environmental problems. Electrocatalytic CO 2 reduction (CO 2 RR) offers the solution for utilising CO 2 as feedstocks for value-added products while potentially mitigating the negative effects. Owing to the extreme stability of CO 2 , selectivity and efficiency are crucial factors in the development of CO 2 RR electrocatalysts. Recently, single-atom catalysts have emerged as potential electrocatalysts for CO 2 reduction. They generally comprise of atomically-and molecularly dispersed active sites over conductive supports, which enable atomiclevel and molecular-level modulations. In this minireview, catalyst preparations, principle of modulations, and reaction mechanisms are summarised together with related recent advances. The atomic-level modulations are first discussed, followed by the molecular-level modulations. Finally, the current challenges and future opportunities are provided as guidance for further developments regarding the discussed topics.

“…This observation is consistent with the previous ECR studies using bicarbonate solution as the electrolyte. 28,58,59 To justify, we eliminated the indirect supply of CO 2 source from bicarbonate solution by performing CPEs in N 2 -saturated 0.1 M K 2 HPO 4 /KH 2 PO 4 . Indeed, only H 2 was liberated for NG and 1-Ni@NG electrodes (Fig.…”
