Unlocking the Activity of Molecular Assemblies for CO₂ Electroreduction in Zero-Gap Electrolysers via Catalyst Ink Engineering.

ABSTRACT: In recent years, CO₂ electrolysis, particularly the electrochemical reduction of CO₂ to CO in zero-gap systems, has gained significant attention. While Ag-coated gas diffusion electrodes are commonly used in state-of-the-art systems, heterogenized molecular catalysts like bis-coordinated homoleptic silver(I) N,N-bis(arylimino)-acenaphthene (Ag-BIAN) complexes are emerging as a promising alternative due to their tunability and high mass activity. In this study, the influence of ink composition on the performance of Ag-BIAN-based GDEs in zero-gap electrolyzers (ZGEs) are systematically explored at 60 °C and 600 mA cm⁻². Sedimentation analyses across various solvents informed the selection of optimal solvent-catalyst and solvent-carbon additive combinations, s
