Hydrogenation and Halogenation of Carbon

On the other hand, the strength of carbon-halogen bonds is lower than carbon-hydrogen bonds, hence recently the halogen-terminated surface is preferred as an activated platform for further modification. 

PPF surface is iodinated by exposing it to iodine plasma. Iodinated surface can then be reacted with different alkene and alkyne compounds in the presence of appropriate 

To extend the hydrogen evolution potential in an aqueous media, a fluorine-terminated diamond surface is prepared in a radio frequency plasma reactor of CF-He [124]. Fluorine-terminated diamond is usually used to study electrode reactions that require high over potential. For covalent attachment of different biomolecules, hydrogen-terminated diamond electrodes are also treated with ammonia plasma to prepare the surface with terminal amine groups [125].
