摘要

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2368m²/g；在300K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。

Abstract: 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 2.9mmol/g at 300K 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-Teller surface area of the PCs.
