Electrochemical formation of methane, ethylene, and ethane with a bimetallic nickel complex: Is CO <sub>2</sub> the source of carbon?
Most molecular CO<sub>2</sub> reduction electrocatalysts generate CO as the only gaseous carbon product. Herein, we report a dinickel complex that produces H<sub>2</sub>, CO, CH<sub>4</sub>, C<sub>2</sub>H<sub>4</sub>, and C<sub>2</sub>H<sub>6</sub> under negative applied potentials. Using <sup>13</sup>C isotopic labelling and high-resolution mass spectrometry, we find that CO and CH<sub>4</sub> originate from CO<sub>2</sub>, C<sub>2</sub>H<sub>4</sub> does not, and the origin of C<sub>2</sub>H<sub>6</sub> remains unresolved.
