“…48 As shown in Figure 3I, Ag 1 /CeO 2 has a larger ECSA than Ag 1 /CeO 2 , Ag NP /CeO 2 , CeO 2 , and CeO 2 -c. This suggests that Ag 1 /CeO 2 exposed more catalytically active sites, leading to higher CO 2 RR to CO performance. 49 The electrochemical impedance spectroscopy (EIS) results at open circuit potential in a CO 2 -saturated electrolyte are shown in Figure S30. As expected, Ag 1 /CeO 2 show the lowest interfacial charge transfer resistance (R ct ), which indicates that Ag 1 /CeO 2 has a higher overall electronic conductivity to achieve a high current density of CO 2 electrochemical reduction.…”

Ag single-atom catalysts (SACs) have great potential in selective electrocatalysis of the CO2 reduction reaction (CO2RR) to CO, while it is still a challenge to achieve high current density and high atom efficiency simultaneously. Here, we present a new and simple in situ adsorption–reduction method to prepare Ag SACs supported on CeO2 (Ag1/CeO2). It is found that Ag single atoms are anchored on CeO2 through strong metal–support interaction (SMSI), and each Ag atom is accompanied with three interfacial oxygen vacancies. This Ag1/CeO2 exhibits high performance in the electrocatalytic CO2RR with a high CO faradaic efficiency (FE) of >95% under a wide potential range. The turnover frequency (TOF) value can reach 50,310 h–1 at FECO = 99.5% in H-cells. Notably, Ag1/CeO2 achieves an industrial-grade current density of 403 mA cm–2 with a high FECO of 97.2% in flow cells. Experimental results combined with density functional theory calculation revealed that this superior performance was mainly ascribed to the existence of interfacial oxygen vacancies, which lead to the formation of Ag–O–Ce3+ atomic interfaces, and activates the Ce3+–O structures as the synergistic active center of Ag, thus promoting CO2 adsorption and activation and reducing the reaction potential barrier of *COOH-to-*CO.

“…The electrochemical CO 2 reduction reaction (CO 2 RR) can convert CO 2 into high-value-added chemicals and convert the abundant but intermittent renewable energy into stable and portable chemical fuels, thus providing a promising pathway for a sustainable carbon cycle. − The products of CO 2 RR vary with different metal catalysts, − among which formate represents a kind of important target with wide applications and high production value per electron. − Several main group metals (e.g., Bi, − Sn, − In − ), exhibit relatively high activity and selectivity toward formate for CO 2 RR in aqueous solutions and are now being intensively studied due to their high abundance and low cost . For instance, bismuth nanocatalysts and their derivatives exhibited enhanced formate evolution selectivity, activity, and stability for CO 2 RR due to the rational modification of their structures, morphologies, as well as the compositions and structures of their heterostructures. − However, the further improvement of CO 2 RR activity and selectivity of bismuth catalysts for practical applications still face considerable challenges, including weak CO 2 adsorption, low electrical conductivity, slow mass transfer for CO 2 molecules, and so forth.…”

Electrochemical CO2 reduction reaction (CO2RR), which uses renewable electricity to produce high-value-added chemicals, offers an alternative clean path to the carbon cycle. However, bismuth-based catalysts show great potential for the conversion of CO2 and water to formate, but their overall efficiency is still hampered by the weak CO2 adsorption, low electrical conductivity, and slow mass transfer of CO2 molecules. Herein, we report that a rationally modulated nitrogen-doped graphene aerogel matrix (NGA) can significantly enhance the CO2RR performance of bismuth nanoplates (BiNPs) by both modulating the electronic structure of bismuth and regulating the interface for chemical reaction and mass transfer environments. In particular, the NGA prepared by reducing graphene oxide (GO) with hydrazine hydrate (denoted as NGAhdrz) exhibits significantly enhanced strong metal–support interaction (SMSI), increased specific surface area, strengthened CO2 adsorption, and modulated wettability. As a result, the Bi/NGAhdrz exhibits significantly boosted CO2RR properties, with a Faradaic efficiency (FE) of 96.4% at a current density of 51.4 mA cm–2 for formate evolution at a potential of −1.0 V versus reversible hydrogen electrode (vs RHE) in aqueous solution under ambient conditions.
