Photocatalytic efficiency of iron oxides: Degradation of 4-chlorophenol
Original language description
The photocatalytic activity of ferrihydrite Fe5O7(OH) x 4H(2)O synthesized by homogeneous precipitation with urea and products obtained by calcinations of as-precipitated ferrihydrite at different temperatures (200-1000 degrees C) was studied. The microstructure and surface properties of raw precipitate and all heated samples were characterized by means of HRTEM, SEM, BET/BJH and RTG analyses. Kinetics of disappearance of 4-chlorophenol (4-CP) in aqueous solution was used as a test reaction. We have found that hematite Fe2O3 obtained at 1000 degrees C exhibited satisfied photocatalytic efficiency on the degradation of 4-CP.
