“…Finally, the low price of transition metal compound catalysts increases the potential for large-scale applications compared with precious metal catalysts. 108 Figure 5a shows preparation procedures and microstructure for Fe−Cu−N−C. The new catalyst showed high surface adsorption state and promoted fission of the C=O bonds, owing to high densities of (bimetallic) active sites.…”

“…Its unique coordination structure and unsaturated coordination environment can improve the electrocatalytic performance. While Cu–N x was found to have poor electrocatalytic performance, recent studies by Xu et al constructed bimetallic active site systems by introducing a second atom (iron) to tailor the microstructure of electrocatalysts and change the chemical and electronic performance Figure a shows preparation procedures and microstructure for Fe–Cu–N–C.…”

Heterogeneous electrocatalysis is one of the most promising ways to advance the development of metal–CO2 batteries and CO2 electrolysis technologies. Although both research areas rely upon efficient electrochemical reduction of CO2, to date the respective research has been largely carried out independently. This Focus Review introduces the latest innovative design strategies toward heterogeneous electrocatalysts applied for both metal–CO2 batteries and CO2 electrolysis. The structural design of various categories of catalysts, their synthesis methods, and electrocatalytic reactions are discussed in detail. The review also presents a discussion of the fundamental reaction mechanisms active for both applications. Finally, we will reflect on the challenges and new opportunities for each category of electrocatalysts. We hope to provide researchers a more comprehensive understanding of the design of high-performing electrocatalysts to advance both metal–CO2 batteries and CO2 electrolysis technologies.

“…In the high temperature environment, Fe 3+ was gradually reduced by the surrounding graphitized C and bonded with the adjacent Co, thus forming the Fe and Co bimetallic active sites. [ 116 ] At the same time, the Fe‐catalyzed support generates nitrogen‐doped graphitized carbon, which decomposes and releases C and N fragments, accelerating the fracture of the metal–imidazole–metal bond and thus forcing the generation of voids in the MOF (see Figure a–g). Finally, the cavity structure is formed under the action of Kirkedall.…”

In recent years, some experiments and theoretical work have pointed out that diatomic catalysts not only retain the advantages of monoatomic catalysts, but also introduce a variety of interactions, which exceed the theoretical limit of catalytic performance and can be applied to many catalytic fields. Here, the interaction between adjacent metal atoms in diatomic catalysts is elaborated: synergistic effect, spacing enhancement effect (geometric effect), and electronic effect. With regard to the classification and characterization of various new diatomic catalysts, diatomic catalysts are classified into four categories: heteronuclear/homonuclear, with/without carbon carriers, and their characterization measures are introduced and explained in detail. In the aspect of preparation of diatomic catalysts, the widely used atomic layer deposition method, metal–organic framework derivative method, and simple ball milling method are introduced, with emphasis on the formation mechanism of diatomic catalysts. Finally, the effective control strategies of four diatomic catalysts and the key applications of diatomic catalysts in electrocatalysis, photocatalysis, thermal catalysis, and other catalytic fields are given.

Electrochemical carbon dioxide (CO2) conversion technologies have become new favorites for addressing environmental and energy issues, especially with direct electrocatalytic reduction of CO2 (ECO2RR) and alkali metal‐CO2 (M–CO2) batteries as representatives. They are poised to create new economic drivers while also paving the way for a cleaner and more sustainable future for humanity. Although still far from practical application, ECO2RR has been intensively investigated over the last few years, with some achievements. In stark contrast, M–CO2 batteries, especially aqueous and hybrid M–CO2 batteries, offer the potential to combine energy storage and ECO2RR into an integrated system, but their research is still in the early stages. This article gives an insightful review, comparison, and analysis of recent advances in ECO2RR and M–CO2 batteries, illustrating their similarities and differences, aiming to advance their development and innovation. Considering the crucial role of well‐designed functional materials in facilitating ECO2RR and M–CO2 batteries, special attention is paid to the development of rational design strategies for functional materials and components, such as electrodes/catalysts, electrolytes, and membranes/separators, at the industrial level and their impact on CO2 conversion. Moreover, future perspectives and research suggestions for ECO2RR and M–CO2 batteries are presented to facilitate practical applications.
