摘要
The composite photocatalyst, N-TiO2 loaded with Ni2O3, was prepared by N-2 plasma treatment. X-ray diffraction, X-ray fluorescence, N-2 adsorption, UV-vis spectroscopy, photoluminescence, and X-ray photoelectron spectroscopy were used to characterize the prepared TiO2 samples. The results indicated that the band gap energy was decreased obviously by nitrogen doping, whereas loading of Ni2O3 did not influence the band gap and visible light absorption. The photocatalytic activities were tested in the degradation of 2,4,6-trichlorophenol (TCP) under visible light. The photocatalytic activity and stability of composite photocatalyst were much higher than that of catalyst modified with nitrogen or Ni2O3 alone. The synergistic effect of doping nitrogen and Ni2O3 over TiO2 was investigated.
