It is necessary to develop a safe and efficient technique for disinfection of drinking water to prevent waterborne pathogens of infectious diseases. In this study, ZnO nanoarray electrodes with different sizes were investigated for low-voltage and high-efficiency electroporation disinfection. The results showed that ZnO nano-pyramid with small tip width and proper length achieved over 99.9% disinfection efficiency against Escherichia coli under 1V and a flow rate of 10 mL/min (contact time of 1.2 s). The suitable size of the nanoarray for electroporation disinfection was optimized by establishing the correlation between four kinds of ZnO nanoarrays and their efficiency, which can guide the preparation of next-generation electroporation-disinfecting electrodes.
