| Abstract: | Nanostructured N-doped TiO2 photocatalyst has been prepared via a new approach from Ti-based MOFNH2-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 0.018 min-1 than that of the TiO2-P25 and TiO2 under the visible light. |
