Developing selective and durable catalysts is essential for CO₂ conversion into value-added chemicals and fuels. Hybrid catalysts, formed by anchoring molecular catalysts onto electrode surfaces, retain the advantages of molecular catalysis while enabling reactions in benign aqueous conditions. In this work, a series of manganese bipyridine complexes adorned with varying numbers of diethylamine pendants (zero to four) were immobilized on multi-walled carbon nanotubes (MWCNT) to serve as hybrid catalysts for electrochemical CO₂ conversion.
