Disinfection of E.coli using visible-light-driven photocatalyst

摘要：

　　Ag/BiOI composites were synthesized by a solvothermal process and subsequent photodeposition method.The prepared Ag/BiOI photocatalysts were characterized by X-ray diffraction (XRD),scanning electronic microscopy (SEM),energy dispersive spectrometer (EDS),transmission electron microscopy (TEM),X-ray photoelectron spectroscopy (XPS),and UV-vis diffuse reflectance spectra (DRS) measurement.The experimental results showed that the photocatalytic disinfection efficiency of E.coli using visible-light-driven Ag/BiOI was almost 99.99%,and significantly higher than that of BiOI.The determination of of released K+ further confirmed that the cell membranes of E.coli were ruptured in the photocatalytic disinfection.
