    CO<sub>2</sub> Conversion to Formic Acid

## Description

- description: A copper−zirconia composite having an evenly distributed lamellar texture,
    Cu#ZrO2, was synthesized by promoting nanophase separation of the Cu51Zr14 alloy
    precursor in a mixture of carbon monoxide (CO) and oxygen (O2). High- resolution
    electron microscopy revealed that the material consists of interchangeable Cu
    and t-ZrO2 phases with an average thickness of 5 nm. Cu#ZrO2 exhibited enhanced
    selectivity toward the generation of formic acid (HCOOH) by electrochemical reduction
    of carbon dioxide (CO2) in aqueous media at a Faradaic efficiency of 83.5% at
    −0.9 V versus the reversible hydrogen electrode. In situ Raman spectroscopy has
    revealed that a bifunctional interplay between the Zr4+ sites and the Cu boundary
    leads to amended reaction selectivity along with a large number of catalytic sites.
