玉米芯基多孔炭活化制备及表面修饰对其电化学性能的影响研究
Study on the Preparation of Corn Cob Based Porous Carbon Activation and the Influence of Surface Modification on Its Electrochemical Properties
摘要
Abstract
Biomass based porous carbon was prepared using corn cob as raw material,and the effects of activa-tion process and p-phenylenediamine(PPD)modification on the electrochemical properties of porous carbon were investigated.As the dosage of activator increases,the specific surface area of the material first increases and then decreases,and the micropores first decrease and then increase.Surface modification of PPD signifi-cantly improves the specific capacity of C-1∶1 compared to C-1∶2,and the effect of PPD content on specific ca-pacity shows an increasing and then decreasing relationship.The C-1∶1@50％magnification performance is the best,with a scanning rate of 5 mV·s-1 corresponding to a specific capacity of 392.7 F·g-1,which is signifi-cantly higher than other samples.关键词
