Research Abstract

Photocatalytic activity under visible light irradiation was examined for anatase-type N-F-codoped titanium oxide photocatalysts with oxygen vacancy, which were produced either by drip thermal treatment in a fluidized bed (DTFB) or by thermal treatment in an electric furnace under reducing atmospheres. Photocatalytic activity was evaluated by methylene blue decoloration tests or gaseous acetaldehyde degradation tests. Characterization of the prepared photocatalyst samples revealed that the N-F-codoped photocatalyst prepared at 773 K by DTFB exhibited the highest BET surface area of more than 100 m^2/g, which was about three times larger than that by an electric furnace, and its photocatalytic activity was higher than any other photocatalysts prepared in this study.
