摘　　要：碳材料是超级电容器中研究最广泛的电极材料之一[1]。对碳材料进行杂原子掺杂能有效改变其能量状态、电导性及表面润湿性,提高其电化学性能[2]。本文以聚苯乙烯(PS)为模板,多巴胺为碳源和氮源,掺杂过渡金属离子Fe ^(3+)以修饰改性,再对其进行形貌表征及电化学表征,结果显示:包覆时间为1 h时,双掺杂中空碳微球电化学性能最佳,在电流密度为0.1 A/g时,比电容可达13.89 F/g,充放电循环100圈后比电容仍可保留初始值的90%以上。Traditional carbon materials have become one of the most widely studied electrode materials in supercapacitors[1].Studies have shown that heteroatom doping of carbon materials can effectively change its energy state,electrical conductivity and surface wettability,which is beneficial to improve its electrochemical performance[2].Using polystyrene as the template,dopamine as the carbon source and nitrogen source,doping with transition metal ion Fe ^(3+)for modification,and products 1 h morphology was characterized,and their electrochemical performance test was studied.The results showed that when the coating time was one hour,the electrochemical performance of double-doped hollow carbon microspheres was the best,when the current density was 0.1 A/g,the specific capacitance could reach 13.89 F/g,and the specific capacitance can still retain 90%of the initial value after 100 cycles of charge and discharge.
