Electric-field-induced catalytic oxidation, Benzohydrol, Titania,


Electric-field-induced oxidation of benzhydrol to benzophenone over conducting surface containing titanium dioxide has been carried out by using
hydrogen peroxide as oxidant. The results suggest the occurrence of synergistic effect of electric field and titania in which the interphase area between the
titania particles and conducting surface is the most active region for the reaction. The electrical field on the generation of surface charge to induce the
adsorption of organic substrate has also been confirmed by dye adsorption experiments.
