With the rapid development of economy, water pollution becomes a serious threat to people's lives and health. It is urgent to exploit a method to achieve rapid and long-term stability water disinfection. Herein, the branched CuO-Co₃O₄ nanowires (NWs) were first prepared on the foamed copper substrate, afterwards coated a layer of carbon film on NWs to obtain the innovative CuO-Co₃O₄@C NWs filter, which remarkably elevated the sterilization property and superior long-term stability. As a result, the resulting CuO-Co₃O₄@C NWs filter, based on electroporation and reactive oxygen species (ROS) sterilization technology, had an extremely sterilization efficiency of 99.5% for Escherichia coli and Staphylococcus aureus at a flow rate of 1000 mL min^-1 and an external voltage of 10 V. More importantly, the filter had excellent bactericidal stability. After 12 hours of continuous operation, the efficiency remained above 80%, which was not possible with the previously reported electroporation technology. This rapid and long-time stability water disinfection material has great potential in practical applications in the future.

随着经济的快速发展，水污染已成为威胁人们生命和健康的严重威胁。迫切需要开发一种能够实现快速，长期稳定的水消毒的方法。在此，首先在泡沫铜基板上制备分支的CuO-Co ₃ O ₄纳米线（NWs），然后在NWs上覆盖一层碳膜以获得创新的CuO-Co ₃ O ₄ @C NWs过滤器，该过滤器显着提高了杀菌性能和出色的长期稳定性。结果，基于电穿孔和活性氧（ROS）灭菌技术的所得CuO-Co ₃ O ₄ @C NWs过滤器对99.5％的微生物具有极高的灭菌效率。大肠杆菌和金黄色葡萄球菌的流速为1000  mL  min ^-1，外部电压为10V  。更重要的是，该过滤器具有出色的杀菌稳定性。 连续运行12小时后，效率保持在80％以上，这是以前报道的电穿孔技术无法实现的。这种快速且长期稳定的水消毒材料在未来的实际应用中具有巨大的潜力。
