摘要(Abstract)：

为了改善碳材料的性质，以间苯二酚、甲醛为碳源，盐酸胍为氮源，聚氧乙烯-聚氧丙烯-聚氧乙烯（F127）为软模板剂，采用扩展的stöber法合成间苯二酚-甲醛-盐酸胍胶体球（NPS），然后水热、碳化制备掺氮碳球（NCS），考察了盐酸胍加入量对样品的结构特点、微观形貌及元素组成的影响，并通过循环伏安、恒流充放电对样品的电化学性能进行测试。结果表明：该方法制备出的掺氮碳球比表面积较大（590.8~851.5 m²·g^-1），粒径均一，含氮量较高（3.142%~5.377%），具有较好的双电层电容器性能。当盐酸胍和间苯二酚的摩尔比为8：1时，制备的碳球电容性能最优。在电流密度为10 A·g^-1时，比电容达到252 F·g^-1，经历1 000次循环后，电容保持率为97.2%。至此，以盐酸胍为氮源，采用扩展stöber法成功制备出了具有优异电化学性能的掺氮碳球。
