Fe2O3 nanoparticles anchored on 2D kaolinite with enhanced antibacterial activity†
Abstract
An enhanced antibacterial activity of Fe2O3 nanoparticles was achieved by controlling the distribution density of Fe2O3 nanoparticles on modified kaolinite nanosheets (Fe2O3–KlnKAc) 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.
