Photoreduction of CO₂ into value‐added fuels is one of the most promising strategies for tackling the energy crisis and mitigating the “greenhouse effect.” Recently, metal–organic frameworks (MOFs) have been widely investigated in the field of CO₂ photoreduction owing to their high CO₂ uptake and adjustable functional groups. The fundamental factors and state‐of‐the‐art advancements in MOFs for photocatalytic CO₂ reduction are summarized from the critical perspectives of light absorption, carrier dynamics, adsorption/activation, and reaction on the surface of photocatalysts, which are the three main critical aspects for CO₂ photoreduction and determine the overall photocatalytic efficiency. In view of the merits of porous materials, recent progress of three other types of porous materials are also briefly summarized, namely zeolite‐based, covalent–organic frameworks based (COFs‐based), and porous semiconductor or organic polymer based photocatalysts. The remarkable performance of these porous materials for solar‐driven CO₂ reduction systems is highlighted. Finally, challenges and opportunities of porous materials for photocatalytic CO₂ reduction are presented, aiming to provide a new viewpoint for improving the overall photocatalytic CO₂ reduction efficiency with porous materials.

太阳能驱动的二氧化碳还原为有价值燃料的金属有机框架材料的关键方面

将CO ₂光还原成增值燃料是应对能源危机和减轻“温室效应”最有前途的策略之一。近年来，金属有机框架（MOF）由于其高CO ₂吸收率和可调节的官能团而在CO ₂光还原领域得到广泛研究。从光吸收、载流子动力学、吸附/活化和光催化剂表面反应这三个主要关键关键角度，总结了MOF光催化CO ₂还原的基本因素和最新进展。CO ₂光还原的各个方面并确定总体光催化效率。鉴于多孔材料的优点，还简要总结了其他三种类型多孔材料的最新进展，即沸石基、共价有机骨架基（COFs基）和多孔半导体或有机聚合物基光催化剂。这些多孔材料在太阳能驱动的 CO ₂减排系统中的卓越性能得到了强调。最后，提出了多孔材料光催化CO ₂还原的挑战和机遇，旨在为提高多孔材料光催化CO _{2还原整体效率提供新的视角。}
