Key Points

Electrochemical reduction yields trace C3 hydrocarbons with hydrogenation-driven route, emphasizing catalyst choice.
Key findings indicate that Cu promotes C2 products via C–C coupling in carbon nanosphere-supported catalysts.
Observation of hydroxide catalysts implies tailored approaches for enhanced electrochemical CO2 reduction results in carbon.
Efficient synthesis methods may enable advanced applications in CO2 reduction and fuel generation.

Implication

Comparative study shows enhanced carbon product formation in electrochemical CO2 reduction using hydroxide catalysts.

Abstract

Ni and Cu hydroxide catalysts are compared for CO 2 electroreduction: Cu promotes C 2 products via C–C coupling, while Ni δ + sites enable a hydrogenation-driven route yielding trace C 3 hydrocarbons.
