摘要 采用Mg (OH)2预填充PAN基膜为前驱体制备了具有多级孔结构的复合碳材料,制备的复合碳材料含有54.1% C、26.8% O、6.2% N和6.5% Mg,可将其用作超级电容器的电极材料和染料吸附剂使用。作为超级电容器时,比电容在1 A/g扫描速率下可达236 F/g,在10 A/g扫描速率下可达206 F/g左右,比电容保持率高达87%。优良的倍率性能与多孔结构的层次性有关。该复合材料作为染料吸附剂使用时,对甲基橙(MO)有很高的吸附能力,当染料质量分数为800 μg/g时,其饱和吸附量可达1 170 mg/g。

Abstract: Carbonaceous composite with hierarchically porous structure is prepared by using Mg(OH)2 pre-filled PAN-based membrane precursor for the first time.The prepared carbonaceous composite contains 54.1% of C,26.8% of O,6.2% of N and 6.5% of Mg.The composite is used as electrode material of super capacitor and dye adsorbent.As it is used to make electrode material for super capacitor,the specific capacitance reaches 236 F·g-1 at a scanning rate of 1 A·g-1,and about 206 F·g-1 at a scanning rate of 10 A·g-1.The retention rate of specific capacitance is as high as 87%.Such an excellent ratio performance is related to the hierarchy of porous structure.As the carbonaceous composite is used as a dye adsorbent,it shows a high adsorption capacity to methyl orange.The saturated adsorption capacity can reach about 1,170 mg·g-1 when the mass content of methyl orange is 800 μg·g-1.The present study provides a simple method to prepare the novel carbonaceous composite for different applications.
