氮硫共掺杂中空纳米炭瓶的可控合成
Controllable synthesis of nitrogen and sulfur co-doped hollow carbon nanobottles
摘要
Abstract
Heteroatom-doped carbon materials have attracted more and more attention due to their excellent electrochemical performance.Using biomass-based compounds (fructose) as carbon source,sodium oleate and three-segment copolymers as soft templates,combined with hydrothermal carbonization method,nitrogen and sulfur co-doped hollow carbon nanoparticles with the unique bottle-like structure are synthesized in situ and controlled.The microscopic morphology,elemental composition and elemental binding morphology of the carbon nanoparticles are analyzed.Carbon nanoparticles have a hollow bottle-like structure and are doped with N/S elements.Based on the microstructure,the evolution mechanism of the growth of the material from the hollow bottle-like structure to the solid peanut-like structure is obtained.In 6 mol/L KOH solution,the electrode prepared by the material has a specific capacitance of 133.2 F/g at a current of 1 A/g in 0-1 V,the capacitance retention rate is 90% after 1000 cycles at a current of 10 A/g.关键词
