Abstract

Mimicking natural photosynthesis, artificial photosynthesis for the reduction of CO₂ into valuable hydrocarbon fuels is a promising approach for solar energy utilization and carbon neutrality. However, great challenges are present in the development of efficient photocatalysts for CO₂ reduction and controlling the selectivity for reduction products. This review summarizes the progress in photocatalyst design strategies to improve the efficiency and selectivity of photocatalytic CO₂ reduction. Six popular modification methods are introduced, namely, creation of defect structures, cocatalyst loading, doping, heterojunction formation, single-atom engineering, and surface organometallic catalysis. The effects of these different strategies on the promotion of light absorption, charge separation and migration and catalyst surface reactions in the process of CO₂ reduction are analyzed. In addition, the latest research results on selective reduction to C₁, C₂, and C₂₊ products in CO₂ and H₂O systems are summarized. Finally, the article delves into the future prospects and inherent hurdles in photocatalyst design, focusing on enhancing the selectivity of CO₂ conversion towards specific products. This review provides insights into the efficiency and selectivity of photocatalytic CO₂ reduction across various photocatalysts, thereby serving as valuable guidance for the advancement of high-performance photocatalysts.

人工二氧化碳光还原：光催化剂设计和产品选择性调节综述

模仿自然光合作用，通过人工光合作用将二氧化碳还原成有价值的碳氢化合物燃料，是实现太阳能利用和碳中和的一种前景广阔的方法。然而，在开发用于还原二氧化碳的高效光催化剂和控制还原产物的选择性方面存在巨大挑战。本综述总结了提高光催化二氧化碳还原效率和选择性的光催化剂设计策略的进展。文中介绍了六种常用的改性方法，如缺陷结构、可催化负载、掺杂异质结形成、单原子工程和表面有机金属催化。分析了不同策略对促进 O2 还原过程中光的吸收、电荷分离和迁移以及催化剂表面反应的影响。此外，还总结了在 CO2 和 H2O 体系中选择性还原为 C1、C2 和 C2+ 的最新研究成果。最后，文章深入探讨了光催化剂设计的未来前景和固有障碍，重点是提高 CO2 向特定产物转化的选择性。这篇综述深入分析了各种光催化剂在光催化二氧化碳还原过程中的效率和选择性，从而为开发高性能光催化剂提供了宝贵的指导。
