Activated carbon is widely regarded as a potential CO₂ adsorbent because of its special texture. Activated carbon captures CO₂ mainly through physical adsorption due to the characteristics of surface structure and pore structure, which makes the adsorbent sensitive to temperature and relatively low in selectivity. In order to solve these problems, much effort has been made in new developments, including synthesis activated carbon‐based composites, which can not only improve its CO₂ capture capacity and stability, but also improve its selectivity. This paper reviews the recent research focused on the activated carbon‐based composites using in postcombustion CO₂ capture. The status and development of activated carbon‐based composites are presented in four parts as activated carbon/metal composite, activated carbon/zeolite composite, activated carbon/metal organic framework composite, and activated carbon/carbon material composite. The details of synthesis method, synthesis condition, modification method, and CO₂ adsorption performance are introduced. Simultaneously, the characteristics, advantages, and potential challenges of the composites are also summarized. This work will provide important parameters in the applications of activated carbon‐based adsorbents for postcombustion CO₂ capture and give suggestions on future research efforts. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

用于捕获二氧化碳的活性炭基复合材料：综述

活性炭由于其特殊的质地而被广泛认为是潜在的CO ₂吸附剂。由于表面结构和孔结构的特性，活性炭主要通过物理吸附来捕获CO ₂，这使得吸附剂对温度敏感并且选择性较低。为了解决这些问题，在新的开发方面做出了很多努力，包括合成活性炭基复合材料，它不仅可以提高其CO ₂捕集能力和稳定性，而且还可以提高其选择性。本文回顾了最近的研究，该研究侧重于燃烧后CO _2中使用的基于活性炭的复合材料捕获。活性炭基复合材料的现状和发展分为四个部分，分别为活性炭/金属复合材料，活性炭/沸石复合材料，活性炭/金属有机骨架复合材料和活性炭/碳材料复合材料。详细介绍了合成方法，合成条件，改性方法和CO ₂吸附性能。同时，还总结了复合材料的特性，优点和潜在挑战。这项工作将为燃烧后CO ₂捕集的活性炭基吸附剂的应用提供重要参数，并为今后的研究工作提供建议。©2021化学工业协会和John Wiley＆Sons，Ltd.
