Bi_2MoO_6空心球的水热沉淀法制备及其光催化性能
Preparation and Properties of Bi_2MoO_6 Hollow Spheres by Hydrothermal Precipitation Method
摘要
Abstract
Colloidal carbon spheres with a hydrophilic surface were synthesized using glucose as a precursor by hydrothermal method.Carbon/Bi2MoO6 hollow spheres were successfully prepared by employing colloidal carbon spheres as template in subsection hydrothermal precipitation method.scanning electron microscopy（SEM）,X-ray diffractometry（XRD）,Fourier transform infrared（FT-IR） spectroscopy and Brumauer-Emmett-Tller（BET）were applied to characterize the morphology and structure of the as-prepared colloidal carbon spheres and Bi2MoO6 hollow spheres.The formation mechanism and reaction process of Bi2MoO6 hollow spheres were proposed.The photocatalytic activity of Bi2MoO6 hollow spheres has been tested on decomposable methylene blue under clarinet lamp.The results showed that Bi2MoO6 hollow spheres were composed of nanocrystals,the thickness was about 30～50nm,and the mean diameter was up to 0.6～0.8μm.The BET surface area of Bi2MoO6 hollow spheres and powders were about 11.315m2/g and 3.378m2/g,respectively.When the initial concentration of methylene blue（MB） was 10mg/L,the degradation rate of MB reached to 91.95% under clarinet lamp for 2.5 h by Bi2MoO6 hollow spheres.关键词
