Abstract
TiN/TiO2 nanoparticle photocatalyst was prepared by ball milling of TiO2 in H2O solution doped with TiN. The photocatalyst was characterized by UV–Vis diffuse reflection spectroscopy, X-ray powder diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Based on the results of the characterization, the mechanism of the increase in photocatalytic activity was investigated. The results show that when the amount of doped TiN is 0.15 wt%, the photocatalytic activity of the TiN/TiO2 is at its peak. Compared with TiO2, the photoabsorption wavelength range of the TiN/TiO2 photocatalyst red-shifts about 30 nm, and the photoabsorption intensity increases as well. The photocatalytic activities of the photocatalyst are higher than that of TiO2 under UV and visible light irradiation. The increase of surface Ti3+ reactive center and the extension of the photoabsorption wavelength are the main factors for the increase in the photocatalytic activity of the TiN/TiO2. Doped TiN neither changes the TiO2 crystal phase nor creates new crystal phase by ball milling.
