Photocatalytic performance of TiO2 nanoparticle doped by transition metal ion

TiO2 and Fe-doped TiO2 nanoparticles were prepared by hydrothermal method in order to study the effect of ion doping (Fe) on enhancing photocatalytic activity of TiO2. The band gap, morphology and specific surface area of TiO2 and Fe-doped TiO2 were investigated by step-wise increasing Fe3+ concentrations from 0.05 to 1.00 wt.%.
