Preparation and Photocatalytic Activity of Bi2WO6 by Hydrothermal Method with Differrent Acid-assited
摘要
Abstract
Bi2WO6 was prepared by hydrothermal method using Bi(NO3)3 · 5H2O and Na2WO4 · 2H2Oas raw materials and NaOH as mineralizer.Samples were characterized by XRD,SEM,TEM,DRS and low-temperature N2 adsorption.Photocatalytic activity of Bi2WO6 was investigated,and the effect of Bi2WO6 by different acid-assisted hydrothermal synthesis (CH3COOH and HNO3) was also evaluated.The results reveal that acid has a significant influence on the microstructure and photocatalytic activity of Bi2WO6.HNO3 inhibits the formation of flower microspheres,makes a red shift in the absorption band and enhances the surface areas of Bi2WO6.The results of photocatalytic test reveal that HNO3 enhance photocatalytic activity of Bi2WO6,while the CH3COOH has an opposite effect.关键词
