摘　　要：A novel photocatalyst, bismuth oxychloride （BiOC1） micro-nano particles with a fine ferrite plate structure, was prepared by a low-cost, simple hydrolytic method. The as-prepared BLOC1 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, HC1 concentration, and heat treatment temperature on BiOC1 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 BiOC1 micro-nano particles prepared with SDBS, the HC1 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.A novel photocatalyst, bismuth oxychloride （BiOC1） micro-nano particles with a fine ferrite plate structure, was prepared by a low-cost, simple hydrolytic method.
