    Abstract

    Various radical initiators were used for investigating the hydrogen abstraction reaction on hydrogenated diamond surface. Benzophenone excited by UV light, which is one of the most popular photosensitizers, could not abstract the hydrogen atoms. Thermally excited α,α′-azobisisobutyronitrile (AIBN), which is one of the most popular radical initiators of azo compounds, could also not abstract the hydrogen atoms. On the other hand, benzoyl peroxide, which is one of the most popular radical initiators of peroxide compounds, could abstract the hydrogen atoms. The reaction rate of the hydrogen abstraction reaction by benzoyl peroxide depended on the species of solvent. The hydrogen atoms in CH2 group on (100) face are more reactive than that in CH3 group on (111) face.
