Photocatalytic decomposition of NH3 over TiO2 catalysts doped with Fe

- Fe doped TiO2 photocatalyst (Fe-TiO2) was prepared by solid state reaction method.
- Pt loaded Fe-TiO2 photocatalyst (Pt/Fe-TiO2) enables higher NH3 photodecomposition.
- Fe3+ leads to the effective use of irradiated light and higher reaction activity.
