CO₂ electrocatalytic reduction to ethylene and its application outlook in food science

The efficient conversion of CO₂ is considered to be an important step toward carbon emissions peak and carbon neutrality. Presently, great efforts have been devoted to the study of efficient nanocatalysts, electrolytic cell, and electrolytes to achieve high reactivity and selectivity in the electrochemical reduction of CO₂ to mono- and multi-carbon (C₂₊) compounds. However, there are very few reviews focusing on highly reactive and selective ethylene production and application in the field of electrochemical carbon dioxide reduction reaction (CO₂RR). Ethylene is a class of multi-carbon compounds that are widely applied in industrial, ecological, and agricultural fields. This review focuses especially on the convertibility of CO₂ reduction to generate ethylene technology in practical applications and provides a detailed summary of the latest technologies for the efficient production of ethylene by CO₂RR and suggests the potential application of CO₂RR systems in food science to further expand the application market of CO₂RR for ethylene production.
