“…With the application of negative potentials, obvious CO 2 adsorption (CO 2ads ) peaks at 532 cm −1 were detected for both catalysts. [ 25 ] Due to the stable morphologies and structures of the two samples during CO 2 RR, the intensity changes of in‐situ Raman spectra are caused by the transformation of adsorbed species other than the changes of the catalysts. For the Cu nanoribbons sample, the intensity of CO 2ads peak goes weaker with decreased reducing potentials, which implies increased CO 2 conversion at lower potentials.…”

The electroreduction of carbon dioxide is a promising strategy to synthesize value‐added feedstocks and realize carbon neutralization. Copper catalysts are well‐known to be active for selective electroreduction of CO2 to multicarbon products, although the role played by the surface architecture is not fully understood. Herein, mesoporous Cu nanoribbons are constructed via in‐situ electrochemical reduction of Cu based metal organic frameworks for the highly selective synthesis of C2+ chemicals. With the mesoporous structure, a high C2+ Faradaic efficiency of 82.3% with a partial current density of 347.9 mA cm−2 is achieved in a flow‐cell electrolyzer. Controlled electroreduction of CO2 with Cu nanoribbons exhibited clearly greater selectivity towards C2+ products than Cu nanoleaves and Cu nanorods without porous structures. Finite difference time domain results indicate that the mesoporous structure can enhance the electric field on the catalyst surface, which increases the concentration of K+ and OH−, thus allowing the authors to promote CO2 reduction pathways towards C2+ products.

“…26 DACs show great potential to form C 2 products because the double active sites facilitate the activation of CO 2 molecules and C-C coupling. 27 C 2 H 4 was synthesized on FeCo@C 2 N and FeFe@C 2 N catalysts at low limiting potentials of À0.63 V and À0.76 V. 28 Han et al 29 constructed a CeO 2 /CuO catalyst to promote the C-C coupling reaction, which resulted in signicant selective and active C 2 products. However, the high surface free energy of a single atom causes it to readily agglomerate.…”

“…Figure 7g shows that CeO 2 can change the oxidation state of Cu 2+ (CuO) to Cu + which is crucial for reduction of CO 2 to C 2+ products [198,199]. In this case, CeO 2 severs as impetus for water activation in CO 2 reduction, which is kinetically in favor of the formation of *CHO and further formation of C 2+ [200]. As for insight into how CeO 2 stabilizes the crucial Cu + species, i.e., specific electron transfer, it still needs to be further explored.…”

Electrocatalytic CO2 reduction reaction (CO2RR) can store and transform the intermittent renewable energy in the form of chemical energy for industrial production of chemicals and fuels, which can dramatically reduce CO2 emission and contribute to carbon-neutral cycle. Efficient electrocatalytic reduction of chemically inert CO2 is challenging from thermodynamic and kinetic points of view. Therefore, low-cost, highly efficient, and readily available electrocatalysts have been the focus for promoting the conversion of CO2. Very recently, interface engineering has been considered as a highly effective strategy to modulate the electrocatalytic performance through electronic and/or structural modulation, regulations of electron/proton/mass/intermediates, and the control of local reactant concentration, thereby achieving desirable reaction pathway, inhibiting competing hydrogen generation, breaking binding-energy scaling relations of intermediates, and promoting CO2 mass transfer. In this review, we aim to provide a comprehensive overview of current developments in interface engineering for CO2RR from both a theoretical and experimental standpoint, involving interfaces between metal and metal, metal and metal oxide, metal and nonmetal, metal oxide and metal oxide, organic molecules and inorganic materials, electrode and electrolyte, molecular catalysts and electrode, etc. Finally, the opportunities and challenges of interface engineering for CO2RR are proposed.
