Abstract: | A novel reaction system consisted of a supported TiO2 film electrode, a Ru−Ti oxide film electrode and air (oxygen) electrode is reported. The air (oxygen) electrode can provide
H2O2 continuously for homogeneous photochemical oxidation reaction on the spot. In this reactor, degradation reaction of aniline
occur from interface of TiO2 film to all solution which is irradiated by ultraviolet ray. The degradation rate of aniline was characterized by measuring
the change of chemical oxygen demand (COD) in solution under different conditions. It was found that the degradation rate
of aniline in the novel system increased apparently as compared with single heterogeneous photocatalysis and homogeneous photochemistry
system. It can be explained in terms of combining acts of heterogeneous photocatalysis and homogeneous photochemistry.
