Kinetic parameters were evaluated by simulation of experimental temperature-programmed reduction spectra of alpha-Fe2O3 and Au/alpha-Fe2O3 systems. It was established that gold influences only the first reduction step Fe2O3 --> Fe3O4, the pre-exponential value for Au/alpha-Fe2O3 being substantially higher than that for alpha-Fe2O3. The presence of hydroxyl coverage entails decreasing of the activation energy of this step.
