摘要
该文以Bi(NO3)3·5H2O和Na2WO4·2H2O为原料通过水热法合成Bi2WO6,重点研究通过改变水合加热时间和溶液酸碱性,不同合成条件对Bi2WO6产物形貌的影响.借助扫描电子显微镜(SEM)对Bi2WO6形貌进行分析.实验结果显示,溶液酸碱性和加热时间均对Bi2WO6的形貌有较大影响,水合加热时间也对其形貌有很大的影响.此外,通过在可见光下降解四环素(TC),探讨了不同合成条件对催化剂性能的影响.实验结果表明,酸碱性会破坏Bi2WO6的结构,进而降低其光催化性能.当水合加热时间为25 h时,Bi2WO6的降解效率最高,降解效果约为50%.
This paper synthesizes Bi_(2)WO_(6)using Bi(NO_(3))_(3)·5H_(2)O and Na_(2)WO_(4)·2H_(2)O as raw materials through a hydrothermal method.By altering the hydration heating time and the pH level of the solution,we investigate the impact of different synthesis conditions on the morphology of the Bi_(2)WO_(6) product.The morphology of Bi2WO6 was analyzed via scanning electron microscopy(SEM).The experimental results indicate that both the pH level of the solution and the heating time have significant effects on the mor⁃phology of Bi2WO6,with the hydration heating time also greatly influencing its structure.By degrading tetracycline(TC)under visible light,the study examined the effects of various synthesis conditions on the catalyst′s performance.The results show that the pH level disrupts the structure of Bi2WO6,thereby reducing its photocatalytic efficiency.When the hydration heating time was 25 h,Bi_(2)WO_(6) exhibited the highest degradation efficiency,achieving a degradation rate of approximately 50%.
