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

A copper-barium-decorated carbon nanotube nanocomposite was designed to promote CO 2 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 cata...

Zusammenfassung:	A copper-barium-decorated carbon nanotube nanocomposite was designed to promote CO 2 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. A copper-barium-decorated carbon nanotube nanocomposite enabled a faradaic efficiency of 71% and partial current density of 355 mA cm −2 at −0.7 V vs. RHE.
