Co2 Reduction Reaction

The lack of a robust and standardized experimental test bed to investigate the performance of catalyst materials for the electrochemical CO2 reduction reaction (ECO2RR) is one of the major challenges in this field of research. To best reproduce and mimic commercially relevant conditions for catalyst screening and testing, gas diffusion electrode (GDE) setups attract a rising attention as an alternative to conventional aqueous-based setups such as the H-cell configuration. In particular a zero-gap design shows promising features for upscaling to the commercial scale. In this study, we develop further our recently introduced zero-gap GDE setup for the CO2RR using an Au electrocatalyst as model system and identify/report the key experimental parameters to control in the catalyst layer preparation in order to optimize the activity and selectivity of the catalyst.
