Abstract

The initial composition and chemical state of nanopowder primary particles obtained by grinding natural diamond and detonation synthesis have been studied by X-ray photoelectron spectroscopy. It has been shown that the primary particles of both nanopowders contain mainly carbon and oxygen atoms. The signals from nitrogen, sulfur, chlorine, and metal atoms in the photoelectronic spectrum do not exceed the noise level. It has been discovered that the proportions of carbon atoms are ∼46.5 and ∼67.8% in the state of the sp³ hybridization, ∼26.8 and ∼17.4% in the state of the sp²-hybridization, and ∼26.7 and ∼14.7% in the composition of the oxygen-containing functional groups in the primary particles of the nanopowders obtained by detonation synthesis and by grinding natural diamond, respectively.

爆轰合成获得的纳米金刚石的X射线光电子能谱

摘要

通过X射线光电子能谱研究了通过天然金刚石的研磨和爆轰合成得到的纳米粉体初级粒子的初始组成和化学状态。已经表明，两种纳米粉末的初级颗粒均主要包含碳和氧原子。光电光谱中来自氮，硫，氯和金属原子的信号不会超过噪声水平。已经发现的是碳原子数的比例是~46.5并在状态~67.8％SP ³杂交，~26.8和在状态~17.4％SP ²通过爆轰合成和通过研磨天然金刚石获得的纳米粉末初级颗粒中含氧官能团的组成分别为约26.7和约14.7％。
