In this study,the hydrothermal method was employed to grow submicron CuS on carbon cloth(CC),and the photoreduction method was used to grow Ag nanoparticles on the CuS submicron flowers,thus forming the Ag/CuS/CC catalytic electrode.The application of Ag/CuS/CC electrode-coupled dielectric barrier discharge(DBD)plasma in the disinfection of pathogenic bacteria in water was studied.The Ag/CuS/CC electrode exhibits strong antibacterial activity,and under an external voltage of 30 V,the degradation efficiency of Bacillus subtilis reaches 99.99%within 15 min without regeneration.After five cycles,the inactivation rate of Bacillus subtilis reached 99.99%within 25 min.The practical applicability of the Ag/CuS/CC-coupled DBD system for treating actual wastewater was evaluated,and the changes in biological toxicity were investigated.The results indicate that the prepared Ag/CuS/CC coupled DBD has great potential for safe disinfection of pathogenic bacteria in water through integrated processes.
