【摘要】 以Bi（NO₃）₃·5H₂O和NH₄VO₃为原料，采用水热合成法制备钒酸铋，同时制备La³⁺掺杂以及La³⁺、Er³⁺掺杂的BiVO₄光催化材料，采用X-射线衍射和扫描电子显微镜进行表征复合材料。通过研究对罗丹明B降解率，评定La³⁺单掺杂以及La³⁺、Er³⁺共掺杂的BiVO₄光催化性能。掺杂的BiVO₄复合催化剂的光降解效率明显提高，最佳条件下的降解率，La³⁺掺杂是86%,La³⁺、Er³⁺共掺杂是90%。更多还原

【Abstract】 La³⁺ prepared by hydrothermal method and La³⁺ and Er³⁺ doped bismuth vanadate matrix composite photocatalytic materials. X-ray diffraction（XRD）, scanning electron microscope（SEM）, were used for characterization. The photocatalytic activity of La³⁺ doped and La³⁺、Er³⁺co-doped BiVO₄ composite catalysts was studied with Rhodamine B as the target degradation material. Results show that the doping modification of catalyst degradation rate: the La³⁺ doping the degradation rate was 86%, La³⁺/Er³⁺ doped degradation rate was 90%.更多还原
