阐述了当前应用最广泛的碳捕集与封存（CCS）技术，对比分析了几种CO₂捕集技术的优缺点，介绍了燃烧后捕集技术中的固体吸附剂活性炭（ACs）。综述了电催化还原CO₂生成异丙醇催化剂的选择以及电化学实验中的反应路径，电催化还原技术因可以闭合CO₂捕获和利用之间的循环，被视为是一种环境可持续的选择。最后，总结并展望了CCS技术和电催化还原CO₂技术的发展前景以及亟待解决的问题。

The most widely used carbon capture and storage (CCS) technologies are described, and the advantages and disadvantages of several CO₂ capture technologies are compared and analyzed.Activated carbon, a kind of solid adsorbent for post-combustion capture technologies are introduced.The selection of catalysts for electrocatalytic reduction of CO₂ to produce isopropanol is introduced, and the reaction pathways in electrochemical experiments are reviewed.Electrocatalytic reduction technology is considered as an environmentally sustainable option because it can close the loop between CO₂ capture and utilization.Finally, the prospects for the development of CCS technology and electrocatalytic CO₂ reduction technology as well as the urgent issues to be addressed are summarized and foreseen.
