Preparation of Visible-Light Active Mn-Doped TiO₂ Photocatalyst and its Photodegradation of Methylene Blue from Solution

Abstract:

Mn-doped TiO₂ nanocrystal photocatalysts were prepared by the sol-gel method using MnSO₄·H₂O as manganese source. The catalysts were characterized by XRD, SEM, EPR, UV-Vis, their photocatalytic activity for methylene blue (MB) degradation was investigated. The results showed that Mn was doped into the crystal lattice of TiO₂, and had no influence on TiO₂ crystal structure; the size of TiO₂ nanoparticle gradually decreased with Mn doping concentration increasing. The Mn-doped TiO₂ catalysts have enhanced absorption in the visible light region, and its visible light absorptivity increased with Mn doping concentration increasing. The UV-Vis showed the Mn-doped TiO₂ showed higher photocatalytic activity than the undoped TiO₂for methylene blue degradation under visible light irradiation. It is also found that the MB photodegradation rate of Mn-doped TiO₂ improved by 46% than that of the undoped TiO₂.
