Abstract

In order to investigate the effect of surface fluorination, nitrogen doped titania plates with dominant {001} facets (abbr. NTP) were prepared by one-pot hydrothermal method in the presence of HF, and then two commonly used methods, calcination treatment and NaOH washing were carried out to get rid of F ions anchored on the surface of NTP. The obtained samples were characterized by XRD, SEM and XPS in detail, and their photocatalytic activities were evaluated by the photocatalytic discoloration of methylene blue and methyl orange under visible light irradiation. The results showed that surface fluorination presented positive effect on the visible-light phtocatalytic activity of NTP. The reason could be attributed to the fact that the fluorinated surface was helpful for the generation of •OH radicals.
