The invention provides a method for preparing a Ti4O7 ceramic electrode, comprising the following steps: S1, preparation of a precursor anatase TiO2 matrix sheet ; S2, high - temperature reduction under H2 atmosphere to prepare Ti4O7 ceramics electrode. The Ti 4 O 7 prepared by the method of the present invention has stable performance, high purity, no titanium oxide passivation layer on the surface, high reactivity, strong absorption effect in the visible spectrum region, and reactive brilliant blue for refractory organic pollutants under visible light. The degradation rate of KN-R reaches 75.28%, and the method of the invention is simple to operate, shortens the production cycle, reduces the production cost, and is easy for large-scale preparation. |
