Abstract

The photocatalytic CO₂ reduction reaction (CO₂RR) represents a promising solution to alleviate environmental and energy issues stemming from CO₂ emissions while simultaneously enabling the production of high-value multi-carbon fuels. However, the efficient generation of multi-carbon products remains challenging due to high kinetic barriers, sluggish C–C coupling processes, and intricate reaction pathways. This review provides a comprehensive overview of the latest advancements in synthesizing C₂₊ products through CO₂ photoreduction, highlighting the crucial role of active site design and the C–C coupling mechanism. Specifically, we emphasize the correlation between the structure of active sites and the key intermediates of C–C coupling, which is fundamental for achieving deep photoconversion of CO₂. Finally, we offer a glimpse into future challenges and prospects, outlining potential directions for the development of CO₂-to-multicarbon photoconversion, aiming to contribute novel insights to this exciting field.

光催化CO2还原多碳产物研究进展

光催化二氧化碳还原反应（CO2RR）是一种很有前途的解决方案，可以缓解由二氧化碳排放引起的环境和能源问题，同时使高价值多碳燃料的生产成为可能。然而，由于高动力学障碍、缓慢的C-C偶联过程和复杂的反应途径，多碳产品的高效生成仍然具有挑战性。本文综述了CO2光还原合成C2+产物的最新进展，重点介绍了活性位点设计和C-C偶联机制的关键作用。具体来说，我们强调了活性位点结构与碳-碳耦合关键中间体之间的相关性，这是实现CO2深度光转化的基础。最后，我们展望了未来的挑战和前景，概述了二氧化碳到多碳光转化的潜在发展方向，旨在为这一令人兴奋的领域提供新的见解。
