摘要 以国产聚丙烯腈(PAN)基碳纤维为原料,采用KOH为活化剂制备PAN基活性碳纤维。测定了不同ACF样品的CO2吸附量,并通过氮气吸附、碘吸附以及红外光谱对所得活性碳纤维的比表面积、孔结构及表面官能团进行表征。研究了活化温度、活化时间和表面改性对活性碳纤维CO2吸附量的影响。结果表明,活化温度是影响活性碳纤维CO2吸附量的主要因素。当活化温度为850℃时,所得活性碳纤维BET比表面积为1235m2/g,微孔比表面积为745 m2/g,在吸附温度为273 K、吸附相对压力P/P0为1时,CO2的吸附量达到87.29 mL/g。 Activated carbon fibers were prepared from PAN-based carbon fiber with KOH activation.The CO2 adsorption of ACF samples was measured,and the surface area,pore structure and surface functional groups are characterized by N2 adsorption,iodine adsorption and FTIR.It shows that the activation temperature,activation time and surface modification of activated carbon fiber affected the CO2 adsorption of ACF.The results showed that the activation temperature of ACF is the major factor for CO2 adsorption of ACF.When the activation temperature is 850 ℃,the BET surface area of ACF is 1235 m2/g,and micropore surface area is 745 m2/g.The CO2 adsorption capacity of this sample is up to 87.29 mL/g,at the adsorption temperature of 273 K and relative pressure P/P0 = 1.
