Abstract

A novel visible light-driven photocatalyst, Zn3(O-H)2V2O7·2H2O/V2O5 nanocomposites were prepared by a simple one-step hydrothermal method using NH4VO3 and Zn(CH3COO)2·2H2O as the starting materials at 180°C. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray photo-electron spectroscopy (XPS), and ultraviolet–visible (UV–vis) diffuse reflectance spectroscopy. Zn3(OH)2V2O7·2H2O/V2O5 co-mposites are irregular nanobelts structure, and the diameter of nanobelts is around 40 nm. The composite photocatalysts exhibit the enhanced visible light photocatalytic properties for degradation of methylene blue.
