【摘要】：利用纳米羟基磷灰石(HAP)为模板,麦芽糖(MO)为碳源,通过固化、炭化等过程,制备有序多孔炭材料(HAP-C)。采用扫描电镜(SEM)、N2吸/脱附以及电化学分析方法等对HAP-C进行物理表征和电化学性能分析。结果显示,HAP/MO的质量比对HAP-C的比表面积、孔结构以及电化学性能有着重要影响。制备的多孔炭呈海绵骨架结构,具有较高的比表面积(1 073.5 m2/g)和大的孔容(3.28 cm3/g)。电化学测试显示,当HAP/MO的质量比为1∶2(HAP-C-1∶2)时,具有较高的质量比电容,在扫描速度为5 m V/s时,质量比电容达198 F/g;倍率性能测试显示,当电流密度增大25倍时,质量比电容保持率为58.0%,显示出良好的倍率性能。
[Abstract]:Using nano-hydroxyapatite (HAP) as template and maltose (MOA) as carbon source, an ordered porous carbon material was prepared by curing and carbonization. The physical characterization and electrochemical properties of HAP-C were studied by means of scanning electron microscope (SEM), N _ 2 adsorption / desorption and electrochemical analysis. The results show that the mass ratio of HAP / MO has an important effect on the specific surface area, pore structure and electrochemical properties of HAP-C. The prepared porous carbon has a sponge skeleton structure with a high specific surface area of 1 073.5 m2 / g) and a large pore volume of 3.28 cm ~ 3 / g 路g ~ (-1). Electrochemical tests show that when the mass ratio of HAP/MO is 1: 2, HAP-C-1: 2), it has a higher mass specific capacitance. When the scanning speed is 5 MV / s, the specific mass capacitance reaches 198F / g, and the ratio performance test shows that when the current density increases 25 times, The mass specific capacitance retention rate is 58.0, showing good performance.
