“…As discussed above, well-designed bimetallic catalysts can improve the selectivity and activity for C 2+ hydrocarbon production. A similar but not identical strategy has also been used to improve the electrocatalytic performance for C 2+ oxygenates (38,93,94). For instance, Ag-incorporated Cu-Cu 2 O catalysts exhibited tunable ethanol selectivity, and the highest ethanol FE was 34.15% (95).…”

“…Since the Cu site is very close to the Ag site in a phase-blended pattern (Ag-Cu 2 O PB ), the formation rate of ethanol intermediates for the phaseblended sample could be promoted in comparison to the phase-separated one (Ag-Cu 2 O PS ), leading to a better ethanol generation performance. Besides ethanol, Cu-Ag bimetallic NPs have also been demonstrated to convert CO 2 to acetate with the addition of benzotriazole (93). At −1.33 V versus RHE, the FE of acetate was 21.2%.…”

Strategies in catalysts and electrolyzer design for electrochemical CO₂reduction toward C₂₊products

In light of environmental concerns and energy transition, electrochemical CO 2 reduction (ECR) to value-added multicarbon (C 2+ ) fuels and chemicals, using renewable electricity, presents an elegant long-term solution to close the carbon cycle with added economic benefits as well. However, electrocatalytic C─C coupling in aqueous electrolytes is still an open challenge due to low selectivity, activity, and stability. Design of catalysts and reactors holds the key to addressing those challenges. We summarize recent progress in how to achieve efficient C─C coupling via ECR, with emphasis on strategies in electrocatalysts and electrocatalytic electrode/reactor design, and their corresponding mechanisms. In addition, current bottlenecks and future opportunities for C 2+ product generation is discussed. We aim to provide a detailed review of the state-of-the-art C─C coupling strategies to the community for further development and inspiration in both fundamental understanding and technological applications.

“…This is because the coupling to form C 2 –C 4 products requires the adsorption of multiple CO 2 molecules on surface and their concerted transformation, and is statistically challenged . Current state‐of‐the‐art electrocatalysts have the maximum selectivity of ≈100% for CO or formate, but only ≈60% for ethylene, ≈40% for acetate, and ≈15% for n ‐propanol . Poor selectivity not only results in ineffective utilization of electrolyzer electricity, but also incurs additional costs for the product separation.…”

Selective CO2 reduction to formic acid or formate is the most technologically and economically viable approach to realize electrochemical CO2 valorization. Main group metal–based (Sn, Bi, In, Pb, and Sb) nanostructured materials hold great promise, but are still confronted with several challenges. Here, the current status, challenges, and future opportunities of main group metal–based nanostructured materials for electrochemical CO2 reduction to formate are reviewed. Firstly, the fundamentals of electrochemical CO2 reduction are presented, including the technoeconomic viability of different products, possible reaction pathways, standard experimental procedure, and performance figures of merit. This is then followed by detailed discussions about different types of main group metal–based electrocatalyst materials, with an emphasis on underlying material design principles for promoting the reaction activity, selectivity, and stability. Subsequently, recent efforts on flow cells and membrane electrode assembly cells are reviewed so as to promote the current density as well as mechanistic studies using in situ characterization techniques. To conclude a short perspective is offered about the future opportunities and directions of this exciting field.

“…Another relevant example of possible significant reduction in the process steps, and carbon footprint, is given by the direct electrocatalytic synthesis of acetic acid or acetate from CO 2 [99,[111][112][113]. Acetic acid is also a large-volume chemical (about 14 Mt.…”

Chemical engineering role in the use of renewable energy and alternative carbon sources in chemical production

There is a demand for new chemical reaction technologies and associated engineering aspects due to on-going transition in energy and chemistry associated to moving out progressively from the use of fossil fuels. Focus is given in this review on two main aspects: i) the development of alternative carbon sources and ii) the integration of renewable energy in the chemical production. It is shown how addressing properly these aspects requires to develop also a) new tools for chemical engineering assessment and b) innovative methodologies for the development of the materials, reactors and processes. This review evidences the need to accelerate studies on these directions, being a crucial element to catalyze the transition to a more sustainable use of energy and chemistry. It is remarked, however, the need to go beyond the traditional approaches, with some examples given. In fact, the presence of radical changes in the way of production is underlined, requiring thus novel fundamentals and applied engineering approaches.
