摘　　要：以金属框架有机物为模板,酚醛树脂为碳质前躯体,合成系列微孔炭。合成的微孔炭比表面积可达2 368 m2/g;在300 K常压条件下,该材料对CO2的饱和吸附量为2.9mmol/g。通过调节碳质前躯体的配比和老化时间,可以控制微孔炭的孔结构;在炭化过程中,挥发逸出的Zn也对基体碳发挥协同活化功能,进而使微孔炭的微孔含量提高。微孔炭对CO2的饱和吸附量随其比表面积的增加而增大。A series of porous carbons （PCs） was synthesized from nonporous metal-organic coordination polymers （MOCPs）, using in-situ polymerized phenol resin as a carbon precursor. The optimized PC has a BET surface area of 2368m2/g and an equilibrium CO2 adsorption capacity of 2.9 mmol/g at 300 K and atmospheric pressure. The porous structure of the PCs can be controlled by the formulations of the carbon precursors and gelation/aging time. Meanwhile, the evaporated Zn from the thermal decomposition of the MOCPs acts as an activation agent during carbonization, which eventually improves the microporosity of the PCs. The CO2 equilibrium adsorption capacity increases with increasing Brunauer-Emmett-TeUer surface area of the PCs.
