摘要

The nitrogen-doped mesoporous TiO2 (meso N-TiO2) have been prepared by the sol-gel method with room temperature ionic liquids (RTIL) (C4mimBF4) as the template. By 1H NMR, interactions between titanium and ionic liquid are observed. The meso N-TiO 2 (10-50 nm) possesses the anatase phase with a pore opening of 5-8 nm observed by TEM. The band gap of the meso N-TiO2 is 2.47 eV as determined by DR-UV/VIS. The meso N-TiO2 has a remarkable activity in photocatalytic degradation of methylene blue under visible light (λ. >400 nm). The extended X-ray absorption fine structure (EXAFS) data show that the Ti-0 and Ti-Ti bond distances in the meso N-TiO2 are 1.96 and 3.02 å, respectively, suggesting that the meso N-TiO2 may be distorted with insertion of nitrogen into the TiO2 matrix.
