Derivative plant-based porous carbon as well as preparation method and application thereof

The invention provides derivative plant-based porous carbon as well as a preparation method and application thereof. The bean sprout biomass is used for preparing the active carbon electrode material for the supercapacitor, so that the uniformity of the prepared active carbon is effectively improved, and a suitable green preparation method and an electrochemical performance optimization mechanism are further explored. Specifically, derivative plants represented by mung bean sprouts are used as precursors of the activated carbon for the super capacitor, a series of related quality improvement and modification work is carried out from two aspects of pore structure adjustment and nitrogen atom doping on the basis, and reference is provided for high-value utilization of biomass and preparation of the activated carbon for the super capacitor; therefore, the method has good practical application value. 本发明提供衍生类植物基多孔炭及其制备方法和应用。本发明利用豆芽类生物质为制备超级电容器用活性炭电极材料，有效提高制备活性炭的均一性，并进一步探索适宜的绿色制备方法及电化学性能优化机制。具体的，本发明以绿豆芽为代表的衍生类植物作为
