“…In an alternative procedure, the Ni 2 –N–C catalyst was prepared via immobilization of 8-quinoline-1 H -pyrazole-3-carboxamide (qpyzc) and nickel(II) acetate on the surface of carbon nanotubes (CNTs) . The dinuclear Ni complex-loaded CNT was pyrolyzed in the presence of dicyandiamide (N source) at 600 °C for 2 h (under an Ar atmosphere), followed by treatment with HCl to remove metal clusters and NPs (Figure ).…”

One of the strategies to mitigate the concentration of CO 2 in the atmosphere and reduce the global warming effect is to capture CO 2 and convert it to synthetic fuels and fine chemicals. Although CO 2 is structurally and chemically stable, the electrochemical transformation has attracted much attention because it offers mild reaction conditions regarding temperature, pressure, and process controllability. Among various electrocatalysts, dualatom catalysts (DACs) have been extensively developed in the past few years due to their unique features for the electrochemical reactions of small molecules. The catalytic activity of DACs in the electrochemical CO 2 reduction reaction (eCO 2 RR) has surpassed single-atom catalysts (SACs) by providing a higher metal loading, two active sites (cf. one active site for SACs), a synergistic effect of adjacent metal atoms, the possibility of tuning the electronic state (adjusting the d-band center), and more possible configuration modes (side-on and side-bridge) for adsorption of CO 2 (cf. only end-on and end-bridge modes for SACs). As a result, both higher reactivity and selectivity in eCO 2 RR can be achieved by breaking scaling relationships with more possible interactions between intermediates and active sites. This review highlights and discusses the recent progress in applying homo-and heteronuclear DACs for eCO 2 RR focusing on the synthesis, characterization, and electrochemical catalytic performance.

“…Consequently, Fe 2 @g-CN showed higher CO 2 RR activity and selectivity. Lu et al reported uniformly anchored Ni 2 dual-atoms on N-doped carbon nanotubes (Ni 2 -NCNT) by modulating the ligands of the precursors for CO 2 RR ( Liang et al, 2023 ). The Ni 2 -N 4 and Ni 2 -N 3 DACs models were developed to reveal the activities of the catalysts.…”

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.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Nevertheless, owing to the high thermodynamic robustness of CO 2 and the kinetically favorable hydrogen evolution reaction (HER), electrocatalytic CO 2 RR has poor activity and product selectivity, and the primary hurdle for CO 2 RR remains the shortage of high-performance electrocatalysts. [15][16][17][18][19] Tremendous efforts have been made over the past several decades to develop different types of transition metal-based electrocatalysts such as transition-metal complexes, 20,21 inorganic nanomaterials, [22][23][24] and organic-inorganic hybrid nanomaterials. [25][26][27] Among them, transition-metal complexes such as Por-, phthalocyanine, and other N 4 − macrocyclic compounds have drawn more attention due to the good establishment of mechanisms for transition-metal complexes, which offers well-defined blueprints for an efficient CO 2 RR.…”
