Cu is a catalyst that can electrochemically reduce CO2 to a variety of industrially important carbon products, but often with poor selectivity and low current density. Alloying Cu with other metals provides a useful strategy to tune product selectivity. In this study, four different metal hydroxides were deposited onto Cu(OH)2 sub-micron-sized rods (SMRs) that were grown on a copper foam by an inexpensive and facile method. This procedure was followed by dehydration to form MOx (M = Cd, Sb, Pb, Zn) on a CuyO SMR surface and then electrochemically reduced to form MCu on the Cu SMR surface. Use of these materials for CO2 reduction achieves enhancement in formate selectivity in the order of Cd > Sb > Pb > Zn with excellent current density (â30 mA cm-2). The role of the four materials in tuning the selectivity toward formate during electrochemical CO2 reduction on these modified Cu SMRs is elucidated.
