We present the results of an experimental study of the formation of HD molecules during exposure of hydrogenated/deuterated nano-sized carbon grains to D/H atoms. The effects of H/D irradiation have been analyzed with infrared spectroscopy and mass spectroscopy. The formation process has been investigated for grain and atom temperatures relevant to astrophysical environments such as diffuse clouds and photodissociation regions. The results indicate that HD formation occurs by abstraction of hydrogen atoms chemisorbed in the aliphatic CH2,3 groups of carbon grains. The formation process does not depend on the atom energy (activationless process), while a dependence of the formation rate on grain temperature is observed.
