As-received detonation DNPs with size about 5 nm were annealed (oxidized) in air at 450°C for 30 min to reduce non-diamond carbon content. Then the annealed DNPs were plasma treated using atmospheric-pressure diffuse coplanar surface barrier discharge in pure hydrogen at power densities of 1.8 and 3.1 W/cm2. While infrared spectra of annealed DNPs were dominated by oxygen containing functional groups, plasma-hydrogenated DNPs revealed increase of bands of C–H stretching vibrations in the region of 2800–3000 cm- 1 with only 5 min of plasma treatment. Prolonged plasma treatments up to 60 min resulted in the increase of C–H stretching vibrations and a decrease of C–O–C groups in the spectral region of 1000–1300 cm-1.
