Abstract The Bi-SnO₂/CM electrocatalytic membrane of Bi-doped SnO₂ was prepared by electrothermal reduction-hydrothermal oxidation method using carbon membrane as the substrate membrane. The structure and properties of the electrocatalytic membrane were characterized by XRS, LSV and CV. The removal performance of the electrocatalytic membrane was evaluated by the removal rate of E. coli. The results show that Bi-SnO₂ can increase the active site of the electrocatalytic membrane. When the molar ratio of Bi/Sn is 0.15, the redox time is 60 min, and the current is 0.2 mA, the performance of the prepared electrocatalytic membrane is the best, the oxygen evolution potential reaches 1.74 V, the electrochemical corrosion time can reach 44.5 h, and the continuous treatment is 5 h. The removal rate of E. coli is still more than 96.1%. The chemical bond with the carbon membrane is combined with the carbon membrane. In addition, the electrocatalytic membrane treatment of E. coli shows superior removal performance. It is indicated that Bi-SnO₂/CM electrocatalytic membrane has a good application prospect in wastewater treatment.

Key words： Bi-SnO₂/carbon membrane electrocatalytic membrane E. coli electrocatalytic oxidation oxygen evolution potential
