N2 - The amination of a diamond surface was investigated by treatment of chlorinated diamond in an ammonia environment at various temperatures. The chlorinated diamond was prepared by irradiating hydrogenated diamond with ultraviolet (UV) light in the presence of elemental chlorine. Diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy of the chlorinated diamond showed a strong peak corresponding to the C-Cl stretching mode, which has not been reported in previous studies on chlorinated diamonds. The types of amines formed on the diamond surface were strongly affected by the temperature used for the reaction. DRIFT spectra of aminated diamonds indicate that amination at room temperature results in formation of NH4+. Amination at 373 K showed DRIFT peaks corresponding to C=N vibration and NH2 scissoring. At an amination temperature of 573 K, most of the nitrogen on the surface was present as imines.
