Method for cooperatively degrading organic matters by visible light photoelectric-Fenton

The invention discloses a method for cooperatively degrading organic matters by visible light photoelectric-Fenton. According to the method, a visible light photoelectric-Fenton system formed by visible light, photocatalysis and electric-Fenton is used and the organic matters are put into the system to be degraded. The method comprises the specific steps of (1) preparing a mesoporous TiO2 thin film electrode; (2) forming the visible light photoelectric-Fenton system; and (3) degrading the organic matters. According to the method, a photocatalysis technology, a photoelectric oxidization technology and a Fenton oxidization technology are combined and the visible light is introduced to form the visible light photoelectric-Fenton system; the self-made mesoporous TiO2 thin film electrode is used in the visible light photoelectric-Fenton system to realize the mutual cooperative effect of the photocatalysis and the electric-Fenton under the visible light, so that the treatment effect on organic pollutants by the whole system is improved.
