In this study, through the BiOI and different quality of PdCl2 reactions, preparation of Pd/BiOCl/BiOI photocatalyst with diffident content of Pd by ultraviolet light reduction method. The synthesis of BiOI from Bi(NO3)3·5H2O and KI by solvent thermal method. The as-synthesized samples were characterized by X-ray diffraction, scanning electron microscopy, Transmission electron microscopy, ultraviolet-visible diffuse reflectance spectroscopy, photoluminescence and X-ray photoelectron spectroscopy. The Photodegradation performence of the photocatalysts were assessed by photodegradation of rhodamine B illuminating with a 350W Xe lamp. The results showed that 3%Pd/BiOCl/BiOI photocatalyst exhibited good photocatalytic activity.
