Visible-light-driven photocatalytic inactivation of Escherichia coli K-12 over thermal treated natural magnetic sphalerite: Band structure analysis and toxicity evaluation
Oxygen deficient yolk–shell BiO2−x microspheres prepared by facile solvothermal method showed great inactivation ability toward Escherichia coli, due to its enhanced light absorption ability and separation ability of photoinduced carriers. Reactive species O2− and H2O2 guaranteed this prominent oxidation ability toward bacterial cells.
Zinc oxysulfide (ZnO0.6S0.4) nanoparticles were prepared and used as an effective visible-light-driven (VLD) photocatalyst for the inactivation of Escherichia coli K-12 for the first time.
