摘要：
Iron-doped titanium dioxide (Fe-TiO2) nanomaterials were prepared with the stable fibrous nanostructure of self-assembled bola-type amphiphilic short peptide KI3E as organic template and aminopropyl triethoxysilane as structure-directing agent via sol-gel process to ensure the simultaneous deposition of the titanium dioxide precursor and iron ions on the surface of the peptide templates. The Fe doped-TiO2 nanomaterials were fully characterized by Transmission electron microscope, UV-vis diffuse reflection spectroscopy, X-ray photoelectron spectroscopy, X-ray diffractometer. The results show that iron ions instead of partial titanium ions in the crystal lattice of titanium dioxide, which narrows the band gap of TiO2 and results in enhanced visible light responses. The test results of photocatalytic degradation of rhodamine B and methylene blue indicated that the Fe doped-TiO2 possessed significantly enhanced photocatalytic performance, compared to the commercial TiO2 (P25), while reached a maximum when the doping content of iron ions was 0.5%. © 2022 Chinese Journal of Materials Research.
