Oxidation of Nanodiamond

One method of oxidizing nanodiamond surfaces has already been presented in Section 5.3.4 as a means of sample purification. The differing reactivity of graphitic and diamond carbon is utilized here. The unordered graphitic structures are oxidized and removed as gaseous products, whereas diamond particles are only modified on their surface. [Pg.373]

An oxidation in air at elevated temperature is feasible, too. In doing so, the temperature must be kept below 500 C to prevent decomposition. In the IR-spectrum a significant increase of the C=0-band at 1778cm is observed, while at the same time the signals of C-H-stretch vibrations at about 2900cm decrease. [Pg.373]
