摘要
NDs粉作为电极材料会使氧化还原物质溶液的电化学活性得到增强,归因于NDs颗粒表面不饱和的sp2键,导致其表面态密度增加.文章以爆轰法合成的纳米金刚石作为样品,通过管式炉烧结改性制备纳米金刚石-石墨核壳材料(NDs@G),以XRD、Raman、TEM以及XPS 一系列检测手段对材料的基本性质进行表征和区分.
Abstract
The excellent chemical and catalytic properties of nanodiamonds(NDs)are con-sidered to be the reason for the existence of sp2 hybrid carbon"impurities".As an elec-trode material,NDs powder enhances the electrochemical activity of redox substance solu-tions,which is attributed to the unsaturated sp2 bond on the surface of NDs particles,leading to an increase in their surface density of states.In this paper,nanodiamonds syn-thesized by detonation method is taken as the sample,preparation of nano diamond Gra-phene core-shell materials(NDs@G)by sintering modification in a tube furnace and its basic properties are characterized and distinguished by a series of detection methods such as XRD,Raman,TEM and XPS.
