Boosting Formate Production from CO₂ at High Current Densities Over a Wide Electrochemical Potential Window on a SnS Catalyst.

ABSTRACT: The flow-cell design offers prospect for transition to commercial-relevant high current density CO₂ electrolysis. However, it remains to understand the fundamental interplay between the catalyst, and the electrolyte in such configuration toward CO₂ reduction performance. Herein, the dramatic influence of electrolyte alkalinity in widening potential window for CO₂ electroreduction in a flow-cell system based on SnS nanosheets is reported. The optimized SnS catalyst operated in 1 m KOH achieves a maximum formate Faradaic efficiency of 88 ± 2% at -1.3 V vs reversible hydrogen electrode (RHE) with the current density of ≈120 mA cm^-2 . Alkaline electrolyte is found suppressing the hydrogen evolution across all potentials which is particularly dominant
