| Abstract |
The aim of this research was investigated on effect of iron content on the performance of co-doped
between iron and nitrogen on titanium dioxide (Fe-N-TiO2) on colored and colorless pollutant degradation. The
catalysts (Fe-N-TiO2) were prepared via the hydrothermal method by single-step without calcination at high
temperature. The activities were tested under both visible and UV irradiations. In this work, the effects of
solution pH and different Fe content (wt%) were examined. The physical and chemical properties of assynthesized
Fe-N-TiO2 such as crystallite size, morphology, specific surface area, element analysis and chemical
composition, and energy bandgap were characterized by X-ray diffraction (XRD), Field Emission Scanning
Electron Microscope (FESEM), N2 absorption-desorption, X-ray photoelectron spectroscopy (XPS) and UV-vis
diffuse reflectance spectroscopy (UV-DRS), respectively. The results found that the anatase crystalline phase is
the main phase with a little rutile phase. The anatase crystallite size was about 10-14 nm. The morphology was a
spherical shape with nanometer size. However, the catalyst with higher Fe contents was obvious in smaller size.
The BET surface area slightly increased with increasing of iron contents. XPS results indicated in the Fe3+and
Fe2+ electronic states because iron could be substitution Ti4+ in the crystalline lattice. Metal and non-metal doped
of Fe and N on TiO2 can reduce the energy band-gap from 3.0 eV to 2.75 eV. The reactive red 120 dye and
paraquat were used as colored and colorless pollutant in photocatalytic degradation under visible and UV
irradiation. The effect of solution pH and iron contents was examined. The mechanism of photocatalytic reaction
of colored and colorless pollutant was purposed as well. |
