Enhancing Electrocatalytic CO2 Reduction Using a System-Integrated Approach to Catalyst Discovery

The presented modelling results in this article show that electrochemical CO2 reduction performed at commercially-relevant current densities will ultimately lead to locally alkaline reaction conditions regardless of the electrolyte, configuration and reasonable mass transport scenarios. Discussed in detail are the large implications that this result has for the CO2 reduction reaction itself, and the current way in which catalysts are designed and tested in different electrochemical cell architectures.
