The method specifically comprises mixing titanium precursor, phthalic acid, and same surfactant in solubilized organic sewage in molar ratio of 1:0.05-0.5:0.01-0.2, dropping solution of acetic acid: absolute ethanol: water with molar ratio of 1:1-10:1-2.5, stirring for 10-300 minutes, allowing to stand for 2-48 hours to form wet gel, drying, calcining to obtain functionalized nano-titanium dioxide, mixing functionalized nano titanium dioxide, carbon material, terpineol, and ethyl cellulose to prepare slurry, uniformly coating on conductive glass, and calcining in oxygen-free environment. USE - The method is useful for preparing functionalized electrode, which is useful for solubilizing organic sewage by photoelectric catalytic treatment (claimed). ADVANTAGE - The method: improves the photoelectric catalytic efficiency and selectivity for organic pollutants, which is conducive to the recycling of residual water after photoelectric catalytic treatment; and solubilizes sewage, which has a large environmental hazard due to the presence of a large number of surfactants and a high concentration of organic pollutants, and it is difficult to treat.
