摘　　要：大气中人为来源的CO_2持续增加,使针对碳捕集和储存的研究势在必行。目前的CCS技术被认为是可持续的碳减排途径。而常用的液胺吸收技术存在副产物危险性大、再生能耗高等缺点。另一种基于膜分离的替代技术又处于起步阶段。因此,研究开始关注开发更实用的固体吸附剂来捕捉燃烧后烟气中的CO_2。炭基材料因其独特的性能在低温、中高压条件下对捕集CO_2受到广泛关注。文章综合概述了低成本的热解炭、活性炭(AC)、金属有机碳骨架材料(MOFs)和纳米碳材料在CO_2捕集中的应用。The continuous increase of anthropogenic CO2 in the atmosphere makes the research on carbon capture and storage imperative.Current CCS technology is considered a sustainable way to reduce carbon emissions.However,the common liquid amine absorption technology has the disadvantages of toxic by-products and high regeneration energy consumption.Another alternative technology based on membrane separation is still in its infancy.Thus,the development of high-efficiency adsorbents has attracted extensive attention and expectations over the past decade.Particularly,Carbon based materials have received much attention,for their unique properties for CO2.In this paper,the application of low-cost pyrolysis carbon,activated carbon (AC),metal organic frameworks(MOFs)and nanocarbon materials in CO2 concentration were summarized.
