ZnO nanoparticles were synthesized by the spray-pyrolysis method. There were exposed to oxygen plasma treatment to increase OH radicals on their surfaces. ZnO nanoparticles were spherical grains with a narrow size range of about 7–10nm, and these small particles agglomerated together to form larger clusters. Synthesized ZnO nanoparticles and a p-25 mixed MB solution exposed to UV illustrate that p-25...
The S-doping caused the photon-to-carrier conversion in the energy region below the band gap of pure TiO 2 . The photocatalyst applications of the S-doped TiO 2 , therefore, are of great importance. Synthesized S-doped TiO 2 powders were characterized by SEM, EDS, XRD, UV–vis, FT-IR and Raman spectroscopy tests. The photocatalytic activity of S-doped TiO 2 powder and...
