Interaction of Chlorine with Hydrogenated Diamond Surface

Abstract
The interaction of chlorine with the hydrogenated diamond surface has been investigated by diffuse reflectance Fourier‐transform Infrared (FTIR) spectroscopy, temperature‐programmed desorption (TPD) spectroscopy, and X‐ray photoelectron spectroscopy (XPS). The hydrogenated diamond surface is chlorinated by thermal reaction in chlorine. Hydrogen chemisorbed on the diamond surface is abstracted by chlorine and the chemisorption of chlorine is yielded. Hydroxyl groups are produced by treatment of the chlorinated diamond with water vapor at room temperature. Amino groups are produced by treatment of the chlorinated diamond with ammonia at 425 °C.
