Abstract
A method of electrochemical reduction of carbon dioxide includes the use of multi-faceted Cu2O crystals as a catalyst to convert CO2 to value-added products. An electrochemical cell for the electrochemical reduction of carbon dioxide includes a cathode including the multi-faceted Cu2O crystals. The multi-faceted Cu2O crystals have at least two different types of facets with different Miller indices. The multi-faceted Cu2O crystals include steps and kinks present at the transitions between the different types of facets. These steps and kinks improve the Faradaic Efficiency of the conversion of carbon dioxide. The multi-faceted Cu2O crystals may be nanosized. The multi-faceted Cu2O crystals may include 18-facet, 20-facet, and/or 50-facet Cu2O crystals.
