Oxidation and reduction of nanodiamond particles in colloidalsolutions by laser irradiation or radio-frequency plasma treatment
Original language description
Functionalized nanodiamond particles (NDs) represent carbon nanomaterial with unique properties for various applications. We report on a new approach to surface modification of NDs by their exposure to radio frequency plasma or laser irradiation plasma directly in aqueous solution. By using grazing angle reflectance FTIR spectroscopy and supporting analysis by XPS, zeta-potential, and Kelvin force microscopy we show that surface chemistry of NDs produced by detonation process (DNDs) or high-pressure high-temperature process (HPHT NDs) works in different way. Moieties on as-received NDs are dominated by COOH and C-O-C groups due to wet chemical cleaning procedures. On DNDs, both RF and LA treatment lead to removal of sp2 shell and additional oxidation of the surface to C-O-C groups. On HPHT NDs the RF treatment leads to reduction of C-O-C groups that are transformed into C-OH and C-H moieties. Thus at least partial hydrogenation of colloidal HPHT NDs seems feasible.
