Abstract

Efficient sterilization by a plasma photocatalytic system (PPS) requires strong synergy between plasma and photocatalyst to inactivate microorganisms while suppressing the formation of secondary pollutants. Here, we report that a PPS constructed from a needle array corona discharge and Au/TiO₂ plasmonic nanocatalyst could remarkably improve the sterilization of Escherichia coli (E. coli) and alleviate formation of the discharge pollutant O₃. At 6 kV, the combination of corona discharge and Au/TiO₂ achieves sterilization efficiency of 100% within an exposure time of 5 min. At 5 kV and an exposure time of 8 min, the presence of Au/TiO₂ improves sterilization efficiency of the corona discharge from 73% to 91% and reduces the O₃ concentration from 0.38 to 0.04 ppm, whereas the presence of TiO₂ reduces the sterilization efficiency and O₃ concentration to 66% and 0.17 ppm, respectively. The Au/TiO₂ in the PPS enables a uniform corona discharge, enhances the interaction between plasma, E. coli and nanocatalysts, and suppresses the formation of O₃. Further, the Au/TiO₂ can be excited by ultraviolet–visible light emitted from the plasma to generate electron–hole pairs, and thus contributes to the formation of reactive radicals and the oxidative inactivation of E. coli. The PPS constructed from a needle array corona discharge and Au-based plasmonic nanocatalyst provides a promising approach for developing high-efficiency sterilization techniques.
