Modification of NiTiO3 visible light photocatalysts using Nb compounds |
| 초록 |
Herein we prepared two types of Niobium-containing photocatalysts, Nb-doped NiTiO3 and Nb2O5/NiTiO3 heterojunction. Nb-doped NiTiO3 was synthesized via modified Pechini method followed by a solvothermal treatment and calcination. Nb2O5/NiTiO3 heterojunctions was synthesized by a hydrolysis-loading method. The structural and optical properties were characterized by XRD, Raman, FT-IR, SEM, TEM, XPS, N2 adsorption/desorption technique, UV–vis spectra and PL spectra. Nb-containing photocatalysts were also examined in the degradation of methylene blue (MB) under visible light irritation to understand the influence of the Nb doping into the lattice structure or Nb2O5 heterojunction structure on the photocatalytic behavior. In the results Nb-doped NiTiO3 exhibited higher photocatalytic activity than pure NiTiO3 while Nb2O5 heterojunction with NiTiO3 caused a decrease in photocatalytic activity. |
