Effect of chemical treatment on the structure of ultradisperse diamond and onion-like carbon Academic Article uri icon


  • Ultradisperse diamond (UDD) is one of the few carbon products that can be produced in large amounts by the detonation method [1, 2]. It has been recently shown that UDD consists of crystalline diamond core of about 45 A covered with a surface structure from sp2-hybridized carbon atoms. The surface structure contains onion-like inner shell, which nearly encloses the core and piles of small graphene sheets [39 4]. Here we studied the effect of extraction conditions and a post- treatment (HTT) in hydrogen atmosphere at high temperatures on the surface …
