“…Another strategy to develop MOF hybrids for electrochemical CO 2 reduction was reported by Kung et al They developed as trategy to embed Cu nanoparticles into aZ r-based MOF, NU-1000,b yi nstalling the single Cu II sites into the NU-1000 thin film through solvothermald eposition in MOF structure (SIM) and the electrochemical reduction process (Figure 7a,b). [31] The production rates and Faradaic efficiencies are shown in Figure 7c [32] The FEs of CH 4 using this strategy are 2-3-fold higher than that of GDE withoutC uM OF at À2.3 Vt oÀ2.5 Vv ersus SCE. Additionally,t he Faradaic efficiency of H 2 reduced to 30 % throught he combinationo ft he Cu MOF andt he GDE.…”

Excessive CO emission due to a large amount of fossil fuel utilization has become a widespread concern, which causes both environmental and energy problems. To solve these issues, electrocatalytic and photocatalytic reduction of CO to produce value-added chemicals have gained immense attention. Recently, metal-organic frameworks (MOFs) and their derived materials with high specific surface areas, controllable pore structures, and tunable chemical properties exhibit promising performance among the reported catalytic materials for CO conversion. This review describes the recent advances on the rational design and synthesis of MOF-based electrocatalysts and photocatalysts for CO reduction. The importance of the catalytic processes is highlighted, followed by systematic understanding of MOF-based catalysts for CO reduction through electrochemical and photochemical approaches. Special emphasis of this review is to introduce basic catalyst design strategies and synthesis methods as well as their resulting electrocatalysts and photocatalysts. One of the major goals is to elucidate the structures and properties that link to their catalytic activity, selectivity, and stability towards to CO reduction. We also outline the challenges in this research area and propose the potential strategies for the rational design and synthesis of high-performance catalysts.

“…Furthermore, metal–organic frameworks (MOFs), which are porous crystalline materials with a 3D framework of metal ions or clusters connected by stiff bi‐ or multipodal organic linkers, are also recognized as important supporting materials. [ 121 ] Tan et al reported a Cu 2 O@Cu‐MOF restructured catalyst with a unique CO 2 ‐adsorption ability and demonstrated outstanding performance with a total FE of 79.4% toward hydrocarbon products. [ 122 ] Figure 8d shows a schematic illustration of the process of Cu 2 O@Cu‐MOF catalyst synthesis.…”

Electrochemical reduction of carbon dioxide (CO2RR) product distribution has been identified to be dependent on various surface factors, including the Cu facet, morphology, chemical states, doping, etc., which can alter the binding strength of key intermediates such as *CO and *OCCO during reduction. Therefore, in‐depth knowledge of the Cu catalyst surface and identification of the active species under reaction conditions aid in designing efficient Cu‐based electrocatalysts. This progress report categorizes various Cu‐based electrocatalysts into four main groups, namely metallic Cu, Cu alloys, Cu compounds (Cu + non‐metal), and supported Cu‐based catalysts (Cu supported by carbon, metal oxides, or polymers). The detailed mechanisms for the selective CO2RR are presented, followed by recent relevant developments on the synthetic procedures for preparing Cu and Cu‐based nanoparticles. Herein, the potential link between the Cu surface and CO2RR performance is highlighted, especially in terms of the chemical states, but other significant factors such as defective sites and roughened morphology of catalysts are equally considered during the discussion of current studies of CO2RR with Cu‐based electrocatalysts to fully understand the origin of the significant enhancement toward C2 formation. This report concludes by providing suggestions for future designs of highly selective and stable Cu‐based electrocatalysts for CO2RR.
