Local hydrophobicity allows high-performance electrochemical carbon monoxide reduction to C₂₊ products.

ABSTRACT: While CO can already be produced at industrially relevant current densities via CO₂ electrolysis, the selective formation of C₂₊ products seems challenging. CO electrolysis, in principle, can overcome this barrier, hence forming valuable chemicals from CO₂ in two steps. Here we demonstrate that a mass-produced, commercially available polymeric pore sealer can be used as a catalyst binder, ensuring high rate and selective CO reduction. We achieved above 70% faradaic efficiency for C₂₊ products formation at j = 500 mA cm^-2 current density. As no specific interaction between the polymer and the CO reactant was found, we attribute the stable and selective operation of the electrolyzer cell to the controlled wetting of the cat
