Drastically enhanced photocatalytic activity in nitrogen doped mesoporous TiO2 with abundant surface states

---

Abstract.
Nitrogen doped mesoporous TiO2 was prepared via a modified two-step hydrothermal route. In contrast
to undoped mesoporous TiO2, nitrogen doped mesoporous TiO2 has superior photocatalytic activity under
both UV and visible light irradiation. Photoluminescence spectra reveal that nitrogen doped mesoporous
TiO2 possesses abundant surface states, which can play a vital role in trapping photoinduced carriers as
evidenced by photoelectrochemical process and prolonging the lifetime of the carriers. The remarkably
enhanced photocatalytic activity in nitrogen doped mesoporous TiO2 is attributed to the generated abundant
surface states.
