废弃粽叶制备N/O/Si自掺杂多孔碳及其电化学性能研究
Preparation of N/O/Si Self-doped Porous Carbon from Used Zongzi Leaves and Its Electrochemical Performance Study
摘要
Abstract
To meet the growing market demand for low-cost supercapacitor electrode materials,the used zongzi packaging leaves were used as a precursor,and a simple one-step KHCO3 activation method was employed to prepare N/O/Si self-doped hierarchical porous carbon under a temperature of 700℃and with a small amount of activator(mass ratio of KHCO3 to zongzi packaging leaves was 1∶1).The symmetric supercapacitor device was assembled by the prepared porous carbon.The microstructure of this material was analyzed and its electrochemical performance was tested.The results showed that this was attributed to the developed pore structure of the prepared porous carbon and the co-doping of N,O,and Si heteroatoms,the symmetric supercapacitor exhibited a specific capacitance of 142.4 F/g at a current density of 0.1 A/g.The specific capacitance retention rate reached 85.94%after 10000 cycles of charge-discharge at 2.0 A/g,demonstrating excellent cycle performance.The work provided the new idea for the comprehensive reuse of used zongzi packaging leaves and the preparation and application of porous carbon doped by multiple hetero elements.关键词
