Copper–barium-decorated carbon-nanotube composite for electrocatalytic CO2 reduction to C2 products

A copper–barium-decorated carbon nanotube nanocomposite was designed to promote CO2 reduction to C2 products (ethylene and ethanol). We achieved a faradaic efficiency of 71% and partial current density of 355 mA cm−2 at −0.7 V vs. RHE. Operando methods revealed catalyst transformation and the cataly...

Summary:A copper–barium-decorated carbon nanotube nanocomposite was designed to promote CO2 reduction to C2 products (ethylene and ethanol). We achieved a faradaic efficiency of 71% and partial current density of 355 mA cm−2 at −0.7 V vs. RHE. Operando methods revealed catalyst transformation and the catalytic mechanism.
