本发明公开了一种氮掺杂分级多孔碳微球，由葡萄糖与含氮化合物经水热反应后活化制备而成，其比表面积较高范围在1160~1791 m2 g‑1，孔径分布均一，且微孔含量高。其制备方法包括以下步骤：1）含氮前驱体的制备，将葡萄糖与含氮化合物加入到水中搅拌均匀后，反应、过滤、洗涤、烘干得到含氮前驱体；2）含氮前驱体的碳化和活化，将含氮前驱体和碱性无机物混合，浸泡在水中，搅拌、烘干后煅烧活化得到氮掺杂改性的分级多孔碳微球；3）氮掺杂分级多孔碳微球的后处理，将氮掺杂改性的分级多孔碳微球用盐酸溶液浸泡、洗涤、过滤、烘干、研磨即可。作为超级电容器电极材料的应用时，比电容值范围在248~407 F g‑1。在超级电容器、锂离子电池和电催化领域具有应用前景。
