摘要

以硝酸钐[Sm(NO₃)₃·6H₂O]和钒酸钠(Na₃VO₄)为原料,采用直接沉淀法在三乙醇胺-丙三醇-乙醇混合有机溶剂体系中制备钒酸钐(SmVO₄)纳米粒子,考察其对罗丹明B的可见光催化降解活性,并对其进行表征。研究结果表明:浓度均为0.05mol/L的Sm(NO₃)₃·6H₂O和Na₃VO₄溶液在三乙醇胺、丙三醇和乙醇体积配合比为 1∶1∶3的溶液体系中反应3.0h获得分散性好、平均粒径约100nm、比表面积103.4m²/g的SmVO₄纳米粒子,SmVO₄纳米粒子对罗丹明B的降解率达到58.7%,具有较好的光催化活性。

Abstract

SmVO₄ nanoparticles were obtained via a direct deposition route in triethanolamine-glycerol-ethanolmixed mixed organic solvent,in which Sm(NO₃)₃·6H₂O and Na₃VO₄ were used as raw materials.The as-prepared SmVO₄ was performed for the photocatalytic degradation of rhodamine B under visible light irradiation.The physical and chemical properties of as-obtained sample were also characterized.Results suggested that SmVO₄ sample with well-dispersion,a uniform particle size of 100nm,and a specific surface area of 103.4m²/g was successfully synthesized under the optimum conditions.The optimum experimental conditions were:volume ratio of triethanolamine,glycerol,and ethanol in above mixed solvent,1∶1∶3;Sm(NO₃)₃·6H₂O concentration,0.05mol/L;Na₃VO₄ concentration,0.05mol/L;reaction time 3h.The degradation rate of rhodamine B by SmVO₄ nanoparticles was 58.7%,which proved that the photocatalytic activity of SmVO₄ nanoparticles was good.
