We mainly studied the antibacterial properties of perovskite. Its structure was evaluated by X-ray
diffractometer (XRD), scanning electron microscope (SEM), and ultraviolet-visible (UV-vis) absorption spectrometer
etc. The antibacterial properties of perovskite to Candida albicans (ATCC10231), Escherichia coli
(ATCC25922) and Staphylococcus aureus (ATCC6538) were investigated by the flask oscillation method. The
results show that the perovskite has strong antibacterial ability, and continued antibacterial properties; its sterilization
rates are 87.00%, 99.50%, 96.22% respectively to these three bacteria.
