“…More than 100 h stability of NiSA/PCFM membrane could also be achieved in two-electrode system ( Supplementary Fig. 21) 34,35 . Moreover, the CO FEs obtained with P-NiSA/PCFM was very close to those of NiSA/PCFM using cathode potentials from −0.3 V RHE to −1.2 V RHE , attaining an optimal value of 87% at −1.0 V RHE ( Supplementary Fig.…”

Carbon dioxide electroreduction provides a useful source of carbon monoxide, but comparatively few catalysts could be sustained at current densities of industry level. Herein, we construct a high-yield, flexible and self-supported single-atom nickel-decorated porous carbon membrane catalyst. This membrane possesses interconnected nanofibers and hierarchical pores, affording abundant effective nickel single atoms that participate in carbon dioxide reduction. Moreover, the excellent mechanical strength and well-distributed nickel atoms of this membrane combines gas-diffusion and catalyst layers into one architecture. This integrated membrane could be directly used as a gas diffusion electrode to establish an extremely stable three-phase interface for high-performance carbon dioxide electroreduction, producing carbon monoxide with a 308.4 mA cm−2 partial current density and 88% Faradaic efficiency for up to 120 h. We hope this work will provide guidance for the design and application of carbon dioxide electro-catalysts at the potential industrial scale.

“…The scale‐up of the synthesis process of SACs is also important for the practical CO 2 RR processes. Recently, Wang group applied Ni SACs into a 10 × 10 cm −2 modular cell using an anion‐exchange membrane and reported a high CO evolution current as high as 8.3 A with a CO production FE of 98.4% and a CO generation rate of 3.34 L h −1 per unit cell . This demonstrated the advantage toward a mass production of CO from CO 2 electrolysis using SACs.…”

Carbon dioxide (CO2) emitted from excess consumption of fossil fuels leads to the rise of CO2 concentrations in the atmosphere. One of the most attractive solutions to cut CO2 emission is the electrochemical reduction of CO2 to produce fuels and build a low carbon emission economy. However, the electrochemical CO2 reduction reaction (CO2RR) is a great challenge due to the activation of the highly stable, linear CO2 molecules, and the process involves proton‐coupled multi‐electron transfer with a high energy barrier. Thus, it is critical to develop efficient and highly stable catalyst materials for CO2RR. Nanoparticle‐based electrocatalysts have been extensively investigated, but the broad size distribution not only limits their activity due to the size‐dependent catalytic properties, but also constrains the selectivity and leads to undesired side reactions. Single‐atom catalysts (SACs), a rising star in the catalytic area, can combine the merits of heterogeneous and homogeneous catalysts, offering outstanding opportunities for CO2RR. The advent of SACs for CO2RR has attracted enormous attention recently, and great effort has been devoted into the area and significant advancements have been achieved in recent years. Here, this mini review updates the development of SACs for CO2RR, and their opportunities and challenges are discussed.

“…To circumvent this issue, a membrane electrode assembly (MEA), which uses a polymer electrolyte instead of aqueous electrolyte inspired by the fuel cell, has been recently adopted in the CO 2 RR device ( Figure 10D). 115,135,138,139 In MEA device, since each configuration determines the overall mechanism and performance, studies are still underway to find on optimal system, such as electrolyte type (eg, acid, neutral, and basic solutions) and its supply state, water supply state, and membrane types (eg, anion exchange membrane and cation exchange membrane). These recent improvements of the GDE-type device design have been actively applied to various CO production catalysts, which achieved similarly high current densities and CO FE, demonstrating the feasibility of scale-up process.…”

The conversion of carbon dioxide (CO2) to valuable fuels and chemicals offers a new pathway for sustainable and clean carbon fixation. Recently, the focus has been on electrochemical CO2 reduction on heterogeneous electrode catalysts, leading to remarkable achievements in the reaction performance. To date, CO2 to carbon monoxide (CO) conversion is considered as the most promising candidate reaction for the industrial market, owing to its high efficiency and reasonable technoeconomic feasibility. Moreover, CO has been proposed as a key intermediate species for further reduced hydrocarbons, which can pave the way for various fuel production. This study sets out to describe recent progress on the electrochemical CO2 reduction to CO in a heterogeneously catalyzed system. The review includes understanding of the catalytic material employed and engineering strategies implemented by adjusting the binding energy of key adsorbates. These material design approaches, such as nanostructuring, alloying, doping, and so forth, have pioneered breakouts in the intrinsic catalytic nature of transition metal elements. Moreover, recent advances in systematic design are summarized, with focus on practical industrial applications. Finally, perspectives on the design of electrocatalyst materials for CO production by electrochemical CO2 reduction are presented.
