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sp^(2)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。The excellent chemical and catalytic properties of nanodiamonds(NDs)are considered to be the reason for the existence of sp^(2)hybrid carbon"impurities".As an electrode material,NDs powder enhances the electrochemical activity of redox substance solutions,which is attributed to the unsaturated sp^(2)bond on the surface of NDs particles,leading to an increase in their surface density of states.In this paper,nanodiamonds synthesized by detonation method is taken as the sample,preparation of nano diamond Graphene 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.
