摘　　要：铋系光催化材料在可见光谱范围内显示出了良好的光降解性能。本论文采用两步水热法实现了BiOX(Cl,Br,I)单体到BiOBr_xI_(1-x)和BiOCl_xBr_(1-x)两类复合光催化剂的转化合成。利用XRD、SEM、UV-vis对样品进行了表征,在氙的照射下,使用罗丹明B的光催化降解评价了产品的光催化性能,测试表明两类复合光催化剂的光催化降解性能较单体BiOX均有较大提高。Bismuth-based photocatalysts exhibit excellent photocatalytic properties in the visible range. Two types of photocatalytic composites BiOBrxI1-x and BiOClxBr1-x were synthesized by two-step hydrothermal method from the BiOX （Cl, Br and I） monomer. The samples were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and UV-vis spectrometer. The photoeatalytie performance was evaluated using the photodegradation of Rhodamine B in an aqueous solution under Xenon lamp. The results indicated that compared with BiOX （ Cl, Br and I） monomer, two types of composites showed much higher photocatalytic performance.
