Ethylene is one of the most widely used chemical compounds. It is readily transformed to a variety of useful products that can replace those derived from fossil sources. Further, the ability to produce ethylene from atmospheric carbon dioxide would significantly assist in the urgent need to stabilize, and ultimately to reduce, the concentration of greenhouse gases in the atmosphere. This review covers the electrochemical reduction of carbon dioxide at copper-based cathodes. The direct production of ethylene is the focus of the review, but it is also relevant to include the important ethylene precursor and intermediate in the carbon dioxide reduction reaction, carbon monoxide. Carbon monoxide can be reduced to ethylene on a copper cathode under similar conditions to carbon dioxide. Ethanol is another potential product of the reduction of carbon dioxide at a copper cathode. It can be readily dehydrated to ethylene, further enhancing the overall yield of ethylene. The aim of the review is to show that there are many interacting parameters that influence the effectiveness and efficiency of the electrochemical reduction of carbon dioxide at copper-based cathodes.

二氧化碳电化学还原制乙烯工艺参数

乙烯是最广泛使用的化合物之一。它很容易转化为各种有用的产品，可以替代来自化石来源的产品。此外，从大气二氧化碳生产乙烯的能力将大大有助于稳定并最终降低大气中温室气体浓度的迫切需要。这篇综述涵盖了铜基阴极上二氧化碳的电化学还原。乙烯的直接生产是审查的重点，但也涉及到二氧化碳还原反应中重要的乙烯前体和中间体一氧化碳。在与二氧化碳相似的条件下，一氧化碳可以在铜阴极上还原为乙烯。乙醇是在铜阴极还原二氧化碳的另一种潜在产物。它可以很容易地脱水成乙烯，进一步提高乙烯的总收率。该综述的目的是表明有许多相互作用的参数会影响铜基阴极二氧化碳电化学还原的有效性和效率。
