The Fe-doped TiO2 catalysts were prepared by the sol–gel
method as below: Dissolve 3 ml of tetraisopropyl orthotitanate
(TTIP) in 50ml of mixture HNO3-ethanol (pH = 3). The
obtained solution must be clear and transparent. Make the
sol by adding Fe(NO3)3 solution over 90 min. The content of
Fe (Fe2O3/TiO2) was adjusted to be 0.025, 0.05, 0.10, 0.50,
1.00 and 2.00 mol.% to obtain catalyst samples symbolized
as 025FeTi, 050FeTi, 100FeTi, 500FeTi, 1000FeTi and
2000FeTi, respectively. The sol was kept at room temperature
until the complete hydrolysis of TTIP and gel has been formed
(24 h). The obtained precipitates were filtered and washed
