Hydrogenation organic functional groups

Fig. 6. Band edge positions of several semiconductors ia contact with an aqueous electrolyte at pH 1 ia relation to the redox (electrode) potential regions (vs the standard hydrogen electrode) for the oxidation of organic functional groups (26,27).

Different organic functional groups (i.e., methyl, methylene, phenyl, and the hydrogen atoms adjacent to the carbonyl carbon in aldehydes and organic add groups) absorb at different frequencies and thus can be easily identified. Similarly, different 13C environments result in different absorption characteristics. For instance, carbon atoms in aromatic compounds absorb different frequencies than do those in carbonyl groups.

A number of electrochemical processes have been employed in an integrated approach for the production of hydrogen peroxide which is subsequently used to oxidize organic functional groups. The electrochemical processes have not only been employed for the preparation of fine chemical intermediates,39 but also for the destruction of organic pollutants in water courses.40...
