N2 - Due to an extraordinary combination of intrinsic properties of diamond nanoparticles (DNPs), there is an increased demand for their usage in various areas. While a broad range of surface termination is often done by wet-chemical, UV-irradiation or plasma treatments, DNPs hydrogenation is still an open issue. Thermal annealing or microwave plasma treatment, both known as high-temperature processes, do not offer satisfactory solutions for DNPs hydrogenation. Here, we report on a new approach for plasma-assisted DNPs hydrogenation at temperatures below 100 °C. 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 powers 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.
