Abstract

An enhanced antibacterial activity of Fe₂O₃ nanoparticles was achieved by controlling the distribution density of Fe₂O₃ nanoparticles on modified kaolinite nanosheets (Fe₂O₃–Kln_KAc) by adjusting the pH value of the reaction system. A proper distribution density of Fe₂O₃ nanoparticles generating higher levels of hydroxyl radicals led to a higher antibacterial activity.
