摘要
Nanostructured N-doped TiO2 photocatalyst has been prepared via a new approach from Ti-based MOF[NH2-MIL-125(Ti)]precursor.The success of N doping enhances light absorption and narrows the bandgap.Moreover,the as-prepared nanostructure is constructed with tiny nanoparticles and resembles a pie-like morphology inherited from the MOF,which accelerates electron transfer.Hence,as a photocatalyst for the degradation of methylene blue(MB)under visible light irradiation,the N-doped TiO2(N-TiO2)nanostructure shows higher photocatalytic activity with a reaction rate constant of 0.018min^-1 than that of the TiO2-P25 and TiO2 under the visible light.
