【摘要】 采用静电自组装法制备K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅复合催化剂，并采用IR、UV、XRD、XPS、SEM、氮气吸附-脱附等进行表征；以龙胆紫为有机污染物进行光催化实验，研究复合催化剂的性能。结果表明，K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅成功复合，仍然保持Keggin结构，且稳定性能良好；在龙胆紫初始质量浓度15 mg/L、K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅用量0.08 g、p H为2的条件下，脱色率可达91.35%。更多还原

【Abstract】 The composite catalyst K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅ was prepared by electrostatic self-assembly method and analyzed by IR,UV,XRD,XPS,SEM and N₂adsorption and desorption.Then the photocatalytic experiment was carried out with gentian violet as an organic pollutant to study the performance of composite catalyst.The results showed that the composite had been successfully synthesized and K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅ retained the original Keggin structure and had good stability.Under the conditions of the initial concentration of gentian violet of 15 mg/L,K₇[Ni（H₂O）W₁₁BO₃₉]/PANI/V₂O₅ dosage of 0.08 g and pH 2,the decolorization rate could reach 91.35%.更多还原
