Abstract [en]

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.
