A novel photocatalyst,bismuth oxychloride (BiOCI) micro-nano particles with a fine ferrite plate structure,was prepared by a low-cost,simple hydrolytic method.The as-prepared BiOCl was characterized by scanning electron microscopy (SEM),thermogravimetric analysis-differential thermal analysis (TGA-DTA),X-ray diffraction (XRD),and UV-vis diffuse reflectance spectra (DRS).The effects of preparation conditions such as sodium dodecyl benzene sulfonate (SDBS) dispersant,HCl concentration,and heat treatment temperature on BiOCl performances were investigated.Moreover,its photocatalytic activity was evaluated on the degradation of methylene orange (MO) and was compared with that of TiO2 (P25).The experimental results confirmed that BiOCl micro-nano particles prepared with SDBS,the HCl concentration of 1.5 mol/L,and the heat treatment temperature of 80℃ exhibited the best performance for the photodegradation of MO solution,and they showed good stability and better photocatalytic activity than P25 photocatalyst.
