CO2 electrolysis to multicarbon products at activities greater than 1 A cm−2
Electrolysis offers an attractive route to upgrade greenhouse gases such as carbon dioxide
(CO2) to valuable fuels and feedstocks; however, productivity is often limited by gas diffusion
through a liquid electrolyte to the surface of the catalyst. Here, we present a catalyst:
ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron
transport. The CIBH comprises a metal and a superfine ionomer layer with hydrophobic and
hydrophilic functionalities that extend gas and ion transport from tens of nanometers to the …
