| description | The nickel-containing titania was synthesized and employed in the photomineralization of . A nickel-modified titania photocatalyst was prepared by photodeposition method with using Degussa-P25 TiO2 particle and nickel chloride as raw materials, respectively. The physical analyses were carried out using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmittance electron microscope (TEM), and photoluminescence spectroscopy (PL), to observe changes in particles following nickel modification. The results showed that Ni does not enter into the crystal lattice and is dispersed onto the surface uniformly. Ni improved the intensity of PL spectra with an appropriate Ni content on the surface. The modified titanium dioxide with 0.1 mol% of nickel exhibited two times the -removal activity of bare under ultraviolet illumination. The nickel content in this photodeposition process plays an important role in affinity to molecules, recombination rate of electron-hole pair, and content of active site on the surface and therefore affects the optical and photocatalytic properties. |
