基于生物质废料玉米秸秆多孔碳的合成、表征及电容性能研究
|
摘要
以玉米秸秆为碳源、ZnCl_2为刻蚀剂,通过调控玉米秸秆与ZnCl_2的相对用量得到一系列多孔碳材料(YAC-x).利用XRD、Raman、XPS、TEM、N2adsorption-desorption等手段对其进行表征,并利用三电极超级电容器体系测试其电化学性能.结果表明,与未经刻蚀的玉米秸杆碳(YC)相比,所制多孔碳材料具有更丰富的孔结构及更为优异的超级电容性能,其中YAC-4最为突出,当电流密度为1A/g时,比电容为236.8F/g,这是源于其大的孔容(Vp=1.11cm~3/g)和高比表面积(SBET=2060m~2/g).
A series of porous carbon materials(YAC-x)were prepared from corn stalk using ZnCl_2 as etchant by adjusting their relative dosages.The obtained samples were characterized by XRD,Raman,XPS,TEM and N2 adsorption-desorption.Furthermore,a three-electrode supercapacitor system was employed to investigate their electrochemical performance.Comparing with the unetched corn stalk-derived carbon(YC),the resultant porous carbon materials have more abundant pore structure and much better supercapacitor performance.Among them,YAC-4 is the most prominent one,whose specific capacitance is as high as 236.8 F/g at a current density of 1 A/g.This is due to its large pore volume(Vp= 1.11 cm~3/g)and high specific surface area(SBET= 2060 m~2/g).
