In this study, highly effective B-doped, Ni-doped and B-Ni-codoped TiO2 microspheres photocatalysts were directly synthesized via an aerosol-assisted flow synthesis method. The resulting samples were characterized by XRD, SEM, TEM, UV-vis diffuse reflectance spectroscopy, nitrogen adsorption and XPS. The characterizations revealed hollow microspherical structure of the B-doped and B-Ni-codoped TiO2 photocatalysts, while the Ni-doped and undoped TiO2 products consisted of solid microspheres. It was found that the boron dopant was partially embed...
