摘要
烟道气(Flue Gas)是化石燃料(煤炭、石油和天然气)燃烧所排放的混合气,其主要成分包括氮气(N2,~70%)、二氧化碳(CO_2,~15%)、水蒸气(H_2O)等~[1]。每年全球向大气中排放的CO_2高达400亿吨。目前大气中的CO_2浓度已达到了400 ppm~[2],由此带来了严重的气候和环境问题。化石燃料为不可再生能源,而且储量越来越少,随之而来的能源和化工原料短缺问题也将越来越严重。使用多孔材料通过物理相互作用来进行CO_2的吸附分离,具有清洁、再生成本低等特点。尤其碳基材料具有比表面积大、廉价、易于修饰等特点,已经在该领域获得了广泛的关注。本文中,作者从碳材料的骨架化学组成、孔结构调控、表面官能团修饰等方面综合考虑,制备了系列的氮掺杂纳米孔碳基材料。详细研究了多孔碳材料的CO_2静态及动态吸附分离表现,获得了常温常温下CO_2吸附量为4.5 mmol/g,CO_2/N_2分离系数>200的优异性能,具备了潜在的实际应用价值~[3-5]。
The greenhouse gas effect that causes global warming is largely associated with the CO_2 emissions from the burning of fossil fuels in power plants and combustion engines.~([1])It is therefore critical to develop effective methods for CO_2 capture and sequestration(CCS) from post-combustion effluents,such as power plant flue gases that typically comprise 3-15%CO_2 and more than 70%nitrogen(N_2) under a pressure of 1 bar.~([2])We summarize various effective strategies(N-doping,surface functionalization,extra-framework ions,molecular design,and pore size engineering) for enhancing the CO_2 adsorption capacity and selectivity of carbonaceous adsorbents.~([3-6])
