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。
The metal framework of organic matter as a template, phenolic resin for the carbon precursor, synthetic series of microporous carbon. The specific surface area of the synthesized microporous carbon was up to 2 368 m2 / g. Under 300 K atmospheric pressure, the saturated adsorption capacity of CO2 to this material was 2.9 mmol / g. The pore structure of microporous carbon can be controlled by adjusting the ratio and aging time of carbonaceous precursors. In the process of carbonization, the volatilized Zn also exerts a synergistic activation function on the carbon of the matrix, so that the micropore content of microporous carbon improve. The saturated adsorption amount of CO2 on microporous carbon increased with the increase of specific surface area.
