Abstract Astainless steel-based manganese dioxide electrode ([BMIM][BF₄]-MnO₂@SS) was prepared by hydrothermal method with the aid of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF₄]). The crystal morphology, structure, and electrochemical performance were characterized by SEM, XRD, electrochemical workstation, respectively. The results show that the addition of BF₄ significantly improves the compactness of the electrode surface. It promotes the deposition of MnO₂ on the surface of stainless steel, and increases the oxygen evolution potential and electrochemical activity of the electrode. Electrochemical removal experiments were carried out on 20 mg/L ofloxacin wastewater at a vol-tage of 3 V with [BMIM][BF₄]-MnO₂@SS as the anode and SS electrode as the cathode. The experimental results show that when the reaction time is 30 min, the removal rate of ofloxacin wastewater reaches 89.00%, and the COD_Cr removal rate reaches 72.56%. At the same time, the energy consumption of degrading ofloxacin was reduced by 51.15%. In addition, the accelerated life test showed that the [BMIM][BF₄]-MnO₂@SS electrode life is 1.90 times than that of the MnO₂@SS electrode, and exhibited excellent performance in degrading the ofloxacin wastewater.
