The effect of thermal treatment on the composition of oxygen-containing functional groups in natural (NND) and detonation (DND) nanodiamonds was studied using FTIR spectroscopy and Boehm titration. It was found that annealing in air at 550 °C alters the ratio of hydroxyl and carbonyl groups, removes non-diamond carbon forms, and improves the ordering of the surface structure. The results are consistent with XPS data and confirm the effectiveness of thermal treatment for nanodiamond purification.
