Highly efficient visible-light-induced photocatalytic activity of Bi<inf>2</inf>WO<inf>6</inf>/BiVO<inf>4</inf>heterojunction photocatalysts

The Bi2WO6/BiVO4heterojunction photocatalysts were synthesized by hydrothermal method. Physical properties of the heterojunction photocatalyst samples were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. The XRD results in...
