通过柠檬酸络合法合成硼和铒共掺杂BiVO4，并对其进行XRD、UV-Vis的表征以分析合成材料的物相、形貌。同时考察溶液的初始浓度、pH、催化剂投加量以及光照强度等因素在可见光的照射下对罗丹明B光催化降解的影响。实验结果表明：在50 mL罗丹明B水溶液中，初始质量浓度为10 mg/L，pH=3，催化剂投加量为0.015 g，光照距离14 cm，B-Er共掺杂BiVO4对罗丹明B有较好的光催化活性，反应50 min后，降解率可达90%以上。

Boron and erbium co-doped BiVO4 visible-light-driven photocatalysts have been synthesized by citric acid complex method. The phase,and morphology of the synthetic material are characterized by XRD and UV-Vis. Mean-while,the effects of the factors,such as solution initial concentration,pH,dosage of catalyst,and illumination inten-sity,on the degradation of Rhodamine B under visible light irradiation are investigated. The experimental results show that boron and erbium co-doped BiVO4 has better photocatalytic activity on Rhodamine B degradation under the following conditions:initial Rhodamine B concentration is 10 mg/L,the volume of solution 50 mL,pH 3 of the hydrothermal reaction, dosage of catalyst 0.015 g and light distance 14 cm. After reacted for 50 min,the degradation rate of Rhodamine B can be more than 90%.
