Three-dimensional/two-dimensional (3D/2D) rare earth Ln3+ (Ln = Er or Eu)-doped BiOBr wrapped with reduced graphene oxide (Bi-Ln/rGO) was obtained via a two-step solvothermal–hydrothermal process. The doping of Ln3+ and the construction of heterojunction between 3D Ln3+-doped BiOBr microspheres and 2D rGO nanosheets were beneficial to the wide absorption of visible light and the efficient separation...
Novel visible-light-sensitive BiVO4/Bi2WO6/multi-walled carbon nanotube composites were synthesized using a facile one-pot hydrothermal process. The morphology, physico-chemical properties and specific surface area of the prepared photocatalysts were investigated using field emission scanning electron microscopy(FE-SEM),X-ray diffraction(XRD), UV–vis diffuse reflectance spectroscopy(DRS), transmission...
