Study on Photocatalytic Degradation of Tetracycline with Different Bi2WO6 Morphologies
This paper synthesizes Bi2WO6 using Bi(NO3)3·5H2O and Na2WO4·2H2O 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 Bi2WO6 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,Bi2WO6 exhibited the highest degradation efficiency,achieving a degradation rate of approximately 50％.
