氮掺杂碳片的模板诱导制备及其在超级电容器中的应用
Template Induced Fabrication of Nitrogen Doped Carbon Sheets as Electrode Materials in Supercapacitors
摘要
Abstract
Due to the good electrical conductivity,high specific surface area,and excellent chemical/mechanical stability,carbon nanomaterials with two-dimensional morphology have gradually become the hot topic of the research on supercapacitors.Herein,we report for the first time the fabrication of nitrogen doped carbon sheets (NCSs).In our approach,the sheet-like magnisum aluminum (MgAl) layered double hydroxide was used as the hard template,which was mixed with o-phenylene diamine and iron chloride.The following thermal treatment could render the polymerization and carbonization of o-phenylene diamine.The NCSs with ordered hexagonal architectures were formed by final etching process of the thermally treated mixture.The morphology,structure,graphitic degree,nitrogen content and surface area of the as-prepared NCSs could be adjusted by the temperatures of the thermal treatment.More importantly,the NCSs exhibited outstanding electrochemical performances as the electrode materials in supercapacitors.Among the NCSs,the sample obtained from 600 ℃ (NCS-600) achieved a capacity of 290.0 F· g-1 at a current density of 0.5 A· g-1.After 10000 cycles at 1 A·g-1,the NCS-600 still retained 83％ of its initial capacity,indicating high cycling stability.关键词
