Concerns over the massive increase in CO2 emissions induced by overconsumption of fossil fuels have driven the rapid development of CO2 valorization techniques. Carbon capture and utilization (CCU) technology, which emerged as a promising strategy to relieve increasing environmental concerns and create more carbon feedstocks simultaneously, hold great promise to close the anthropogenic chemical carbon cycle. Herein, recent breakthroughs related to the two predominant techniques involved in returning CO2 into a useful state, namely CO2 capture and CO2 conversion are systematically overviewed. Initially, CO2 capture principles, recent advances, as well as future challenges of state-of-the-art absorbents/adsorbents and membrane separation technology are summarized. Furthermore, innovative catalysts related to the CO2 conversion technologies (including thermo-driven CO2 hydrogenation, photo-and electrochemical CO2 reduction, and enzymatic CO2 conversion) are discussed, emphasis is focused on the catalytic performance, design principles, and economic efficiency. Finally, a perspective regarding the future research opportunities toward CCU technologies is provided. This review aims to stimulate innovation and accelerate interdisciplinary integrations toward CCU related technologies via a discussion of fundamental mechanisms, recent breakthroughs, current associated difficulties as well as future directions.

通过 CO2 Valorization 关闭人为化学碳循环以实现可持续的未来
对化石燃料过度消耗引起的CO 2排放量大幅增加的担忧推动了 CO 2增值技术的快速发展。碳捕获和利用 (CCU) 技术作为缓解日益严重的环境问题并同时创造更多碳原料的有前景的战略而出现，有望关闭人为化学碳循环。在此，系统地概述了与将 CO 2返回到有用状态所涉及的两种主要技术（即 CO 2捕获和 CO 2转化）相关的最新突破。最初，CO 2捕获原理、最新进展以及最先进的吸收剂/吸附剂和膜分离技术的未来挑战进行了总结。此外，与CO 2转化技术相关的创新催化剂（包括热驱动CO 2加氢、光和电化学CO 2还原以及酶促CO 2转化）进行讨论，重点是催化性能、设计原则和经济效率。最后，提供了有关 CCU 技术未来研究机会的观点。本综述旨在通过对基本机制、近期突破、当前相关困难以及未来方向的讨论，刺激创新并加速跨学科整合 CCU 相关技术。
