| description | Cu-based catalysts for efficient C<sub>2+</sub> production from CO<sub>2</sub> electrocatalytic reduction reaction (CO<sub>2</sub>ERR) exhibit significant promise, but still suffer from ambiguous mechanisms due to the intrinsic structure instability during electroreduction. Herein, we report an oxide-derived copper nanowire bundle (OD-Cu NWB) for efficient CO<sub>2</sub>ERR to C<sub>2+</sub> products. OD-Cu NWBs with a well-preserved nanowire bundle morphology lead to promoted multi-carbon production compared to commercial copper powders. The formation of OD-Cu NWBs shows a great dependence on the precipitation/calcination temperatures and per-reduction potentials, which further influence the ultimate CO<sub>2</sub>ERR performance correspondingly. The optimized preparation parameters for the formation of a well-ordered nanowire bundle morphology are found, leading to a preferred C<sub>2+</sub> production ability. Besides the nanowire bundle morphology, the oxide-derived Cu essence of OD-Cu NWBs with stabilized Cu<sup>+</sup> species from per-reduction also promotes the CO<sub>2</sub>ERR activity and facilitates the C-C coupling of key intermediates for C<sub>2+</sub> production. This work provides a facile strategy and inspiration for CO<sub>2</sub>ERR catalyst developments targeting high-valued multi-carbon products. |
