But it also still has some disadvantages such as shorter electrode life poor stability and so on which limit its wider application being limited. In this paper the properties preparation methods modification technologies and application in organic waste water treatments of the Ti-basedSnO 2 electrode were summarized the disadvantages of the electrode and further improvement direction were also discussed.
