摘　　要：Electrosynthesis and carbon dioxide(CO_(2))utilization both have gained interest in recent years due to the efforts to alleviate the climate crisis.Significant progress in the field of electrochemical carboxylation using CO_(2) or electrocarboxylation of organic substrates,particularly organohalides and alkenes,has been made in the past decade.Different components of electrocarboxylation experimental setup as well as the understandings of the mechanism play an important role in the success of the carboxylate syntheses.In this review,overview of the proposed mechanisms and the electrochemical setup are described.The significance of electrochemical components,such as the effect of different cathodes,sacrificial anode materials,and other additives,are explained.The examples of electrocarboxylation for both organohalides and olefins are provided.Lastly,the current trends in the field and future directions are discussed.近年来,人们一直在为缓解气候危机而努力,电合成和CO_(2)利用引起了研究者的广泛关注.在过去十年中,CO_(2)利用或有机物的电羧基化,特别是有机卤化物及烯烃的电羧基化,取得了较大进展.电羧基化实验装置的各组成部分以及深入理解反应机理对羧酸盐的成功合成至关重要.本文概述了电羧基化反应的机理和电化学反应装置,阐明了各装置组成部分的重要性,如不同阴极、牺牲阳极材料和其他添加剂的作用,并以有机卤化物和烯烃的电羧基化反应为例进行了详细讨论.最后,讨论了该领域的发展趋势和未来研究方向.
