Electrochemical reduction of carbon dioxide (CO) has been considered a promising route to reduce net carbon emissions and thus mitigate global warming issues. In practice, it mainly involves two processes including the CO capture and subsequent electrochemical conversion. From the perfective of feasible and economic benefits, it is of practical significance to develop integrated CO capture and conversion systems in an efficient way. However, a majority of studies have been currently focusing on the independent process, and the development of integrated strategies is still in the initial stage. This review mainly covers the recent progress on the integrated technologies of CO capture and electrochemical conversion, including the integration strategies, mechanisms, and corresponding issues. The advantages and disadvantages of those strategies are particularly discussed, aiming to identify the viable routes for future applications. To conclude, the challenges and prospects in terms of the research direction in this field are provided, with the hope of promoting practical CO utilization from the fundamental aspects.
二氧化碳（CO₂）的电化学还原被认为是减少净碳排放从而缓解全球变暖问题的一条有前景的途径。在实际应用中，它主要涉及两个过程，包括CO₂捕获及随后的电化学转化。从可行性和经济效益的角度来看，高效开发集成的CO₂捕获与转化系统具有实际意义。然而，目前大多数研究都集中在独立的过程上，集成策略的开发仍处于初始阶段。本综述主要涵盖了CO₂捕获与电化学转化集成技术的最新进展，包括集成策略、机理及相应问题。特别讨论了这些策略的优缺点，旨在确定未来应用的可行途径。最后，给出了该领域研究方向方面的挑战与前景，希望从基础层面推动CO₂的实际利用。
