Abstract: Perovskite-type V-doped titanium-bearing blast furnace slag (VTBBFS) photocatalyst was prepared by high-temperature solid phase method. The influence of calcination temperature on the photocatalytic and antibacterial properties of VTBBFS was studied in details. Its composition and microstructure were evaluated by X-ray diffractometer, ultraviolet-visible absorption spectrometer, Fourier transform infrared spectrometer and scanning electron microscope. The antibacterial properties of VTBBFS to Candida albicans were investigated by flask oscillation method. The results showed that the optical absorption and antibacterial properties of VTBBFS were the best with 10%(w) doping of vanadium, prepared at 800℃ for 2 h, and its sterilization rate was close to 100% to Candida albicans (ATCC10231). The minimum inhibitory and minimum bactericidal concentrations were 25 and 50 mg/mL. When the concentration was 0.2 mg/mL, the catalyst had the least toxic toxicity.
