An overview of flow cell architecture design and optimization for electrochemical CO₂ reduction

Abstract

Converting CO2 into value-added fuels or chemical feedstocks through electrochemical reduction is one of the several promising avenues to reduce atmospheric carbon dioxide levels and alleviate global warming. This approach...

Microenvironment Optimization towards Electrocatalytic Ammonia Synthesis: Recent Progress and Future

“…As the chambers in the electrochemical cell perform gas phases in the cathode chambers while equipping with gas-diffusion electrodes (GDEs) and flow reactor configurations, the mass transfer limitation can be mitigated by continuously circulating the reactants and products to and away from the electrodes, thus called as "flow cells". [64][65][66][67][68] In this case, the highly-porous gas diffusion layers (GDLs) are introduced between the electrode and the membrane to support the catalyst, thus making the N 2 delivered in the gas phase rather than dissolved in aqueous media, as shown in Fig. 4c.…”

Mechanistic Insights into Formation of CO and C2 Products in Electrochemical CO2 Reduction – the Role of the ECE Mechanism

“…Thanks to intensive recent research activities, the science and engineering of electrochemical CO2 reduction (ECR) has progressed on several fronts including experimental and computational advances in understanding the mechanism, [1][2][3][4] catalyst development, [5][6][7][8] and advances in reactor design such as gas diffusion electrode flow cells and membrane electrode assemblies to achieve industrially relevant current densities. [9][10][11][12] Beyond improving the conversion efficiency (i.e., electrocatalytic activity), directing the reduction of CO2 towards the formation specific valueadded products defines a key goal to bring this process to fruition. [13][14] Copper, by virtue of its unique ability to stabilize reaction intermediates like *CO and *H, enables the formation of higherorder carbon products.…”
