Carbon accumulation has raised worldwide concerns due to the risks of climate change. In such cases, direct carbon dioxide (CO₂) capture and conversion from diluted sources has potential for negative carbon emission. Distinct from non-porous catalytic systems, the fascinating features of large specific surface area, highly exposed catalytic sites, varied structures and tunable functions make porous materials attractive candidates for integrating the process of capture and utilization of diluted CO₂. In this review, we firstly provide a brief overview of the recent developments of porous materials, including zeolites, metal–organic frameworks, porous organic polymers, porous carbon, and functionalized mesoporous materials and their applications for CO₂ adsorption at relatively low partial pressure. Afterwards, direct chemical transformation of diluted CO₂ over different porous catalysts is discussed with the emphasis of their diverse functional roles. This is followed by a brief summary of current challenges and our personal view on future directions of this field.

由于气候变化的风险，碳积累引起了全世界的关注。在这种情况下，来自稀释源的直接二氧化碳 (CO ₂ ) 捕获和转化具有负碳排放的潜力。与无孔催化系统不同，大比表面积、高度暴露的催化位点、多样的结构和可调节的功能等令人着迷的特点使多孔材料成为集成捕获和利用稀释CO ₂过程的有吸引力的候选材料。在这篇综述中，我们首先简要概述了多孔材料的最新发展，包括沸石、金属有机骨架、多孔有机聚合物、多孔碳和功能化介孔材料及其在 CO _{2中的应用。}在相对较低的分压下吸附。_{随后，讨论了稀释的CO 2}在不同多孔催化剂上的直接化学转化，重点讨论了它们不同的功能作用。接下来是对当前挑战的简要总结以及我们对该领域未来方向的个人看法。
