Abstract: The increasingly severe “greenhouse effect” has made the resource utilization of carbon dioxide (CO2) an urgent priority. Compared to other alternative approaches, electrochemical CO2reduction to high-value-added fuels and chemicals powered by renewable electricity offers advantages such as mild operating conditions, environmental friendliness, and high efficiency. This review focuses on CO2-to-ethylene conversion, as ethylene has the largest market demand among CO2reduction products. We first provide a brief introduction to the fundamental reaction mechanisms. Next, we discuss advanced catalyst modification strategies and introduce four representative electrolyzers. We then summarize the current progress in CO2-to-ethylene conversion and highlight the existing scientific and technological challenges. Finally, we conclude with an outlook on the industrial application prospects of CO2-to-ethylene conversion.
