Highly oriented MOF thin film-based electrocatalytic device for the reduction of CO2 to CO exhibiting high faradaic efficiency

Highly oriented MOF thin film-based electrocatalytic device for the reduction of CO2 to CO... A monolithic, highly electrochemically efficient Re-based metal–organic framework (MOF) thin film has been deposited onto a conductive FTO electrode by liquid-phase epitaxy. The X-ray diffraction (XRD) analysis reveals the presence of a highly oriented film grown exclusively along the [001] direction. This epitaxially-grown SURMOF exhibits an extremely high faradaic efficiency of 93 ± 5% when operated as an electrocatalyst for the reduction of CO2 to CO. In addition, the obtained current densities of the high-quality monolithic coatings exceed 2 mA cm−2, a value at least one order of magnitude larger than that reported for previous electrocatalytically active MOF thin films. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Chemistry A Royal Society of Chemistry

Abstract

A monolithic, highly electrochemically efficient Re-based metal–organic framework (MOF) thin film has been deposited onto a conductive FTO electrode by liquid-phase epitaxy. The X-ray diffraction (XRD) analysis reveals the presence of a highly oriented film grown exclusively along the [001] direction. This epitaxially-grown SURMOF exhibits an extremely high faradaic efficiency of 93 ± 5% when operated as an electrocatalyst for the reduction of CO2 to CO. In addition, the obtained current densities of the high-quality monolithic coatings exceed 2 mA cm−2, a value at least one order of magnitude larger than that reported for previous electrocatalytically active MOF thin films.
