摘　　要：分析了一步法与分步法在制备氮掺杂煤沥青基多孔碳材料的结构和储电效能对比。研究表明,一步法因其简便的操作步骤和低能耗而适用于成本敏感的应用,且在使用三聚氰胺作为氮源时,该方法制备的材料展现出优异的电化学性能;分步法制备过程更为复杂和耗能,但其优势在于能够精确控制材料的微观结构和化学性质,尤其是在使用硫酸铵作为氮源时,显示出更佳的电容特性。The structure and electrical storage efficiency of nitrogen-doped coal pitch-based porous carbon materials prepared by one-step method and multi-step method are systematically analyzed.Studies have shown that the one-step method is suitable for cost-sensitive applications due to its simple operation procedure and low energy consumption,and that the materials prepared by this method exhibit excellent electrochemical properties when using melamine as a nitrogen source.Although the multi-step process is more complex and energy consuming,it has the advantage of being able to precisely control the microstructure and chemical properties of the material,especially when ammonium sulfate is used as a nitrogen source,showing better capacitance characteristics.
