A series of titania (TiO 2 )-based nanometer-sized photocatalysts, including nitrogen-doped TiO 2 nanoparticles (NPs), are investigated using X-ray photoelectron spectroscopy (XPS). Conclusive evidence is obtained for O−Ti−N bond formation during the doping process. Therefore, this substitutional doping is held accountable for the significant increase in photocatalytic activity in nitrogen-doped TiO 2 NPs.
