Abstract

[Mn(bpy)(CO)₃Br] cast in a Nafion membrane is an active heterogeneous electrocatalyst with good selectivity for CO₂ reduction to CO in neutral aqueous electrolyte. Addition of multi-walled carbon nanotubes (MWCNT) leads to a ∼10 fold current enhancement and stable CO : H₂ yields (1 : 2) at −1.4 V vs. Ag/AgCl at pH 7.
