The invention belongs to the technical field of photocatalysis electrode materials, and particularly relates to a preparation method for a novel photoelectric catalysis material electrode. The methodincludes the steps that TiO2 nano-Ce is prepared by adopting a sol-gel method, Ti/TiO2NTs are prepared by an anodic oxidation method, and Ti/TiO2/PbO2/TiO2 nano-Ce is prepared by adopting a pulse electrodeposition method. The rare earth element Ce is doped, so that PbO2 particles are smaller, and the specific surface area is obviously increased. Compared with a pure PbO2 electrode, the catalytic activity is higher, the service life is longer, and the stability is better. TiO2 nano-Ce is modified into a nano tube by adopting a pulse electrodeposition method, a Ti/TiO2Nts electrode serving as ananode, a Pt sheet serving as a cathode and a saturated calomel electrode serving as a reference electrode are placed into an electroplating solution containing TiO2 nano-Ce, a special formula is adopted, and a Ti/TiO2/PbO2/TiO2 nano-Ce electrode is prepared through a voltage-stabilized pulse current deposition method. Not only is operation easy, but also the purity, density and uniformity of a deposition layer are improved, the porosity of the electrode is reduced, and the stability and the catalytic performance of the electrode are improved.
