High-rate electroreduction of carbon monoxide to multi-carbon products

Computationally aided, entropy-driven synthesis of highly efficient and durable multi-elemental alloy catalysts

“…The chemical industry and emerging electrochemical energy conversion technologies are generally either thermally or electrically energy intensive and therefore require efficient catalysts to reduce the reaction temperature, pressure, or electrochemical overpotentials (1)(2)(3). In particular, clean energy based on hydrogen (H 2 ), despite being very promising for the replacement of fossil fuels, is largely dependent on advanced catalysts that substantially improve the energy conversion efficiency and decrease material cost (4,5).…”

Structure‐Sensitivity and Electrolyte Effects in CO2 Electroreduction: From Model Studies to Applications

“…C) Partial current density obtained for different products as function of the Cu catalyst and the applied potential vs RHE. Graph adapted from references: [24,37,45,46,77,81,90,91] as highlighted in the legend. The legend also shows the employed electrolyte in any system.…”

“…On the other side, Jouny et al developed a CO flow electrolyser with a GDE that reaches currents densities near to 1 A cm À 2 ( Figure 12B) and and can be operated at 500 mA cm À 2 for 1 hour, being more than 90 % selective towards C2 compounds. [46] Despite the improvement in terms of achievable current densities/efficiencies, the cell potential (the combined needed applied overpotential at both anode and cathode in the electrolyser) for these systems is still too high (higher than 2 V), making the process energetically inefficient. The discussion of the kinetics of the reaction at the anode, typically the oxygen evolution reaction (OER), goes beyond the scope of this review, and we re-direct the reader towards some recent reviews on the topic.…”

“…Here, the complexity of the system increases to include the tuning of the electrolyte composition, the function of ad‐layer structures and the performance of bi‐metallic alloys and shaped nanoparticles. Finally, we discuss how we could build upon this knowledge to identify future research directions, such as the rational design and characterisation of new, advanced electrocatalysts and catalytic configurations, including solutions that aim at closing the gap between laboratory‐based testing setups and industrially‐relevant devices …”
