In this paper, TiO2 and Fe doped TiO2 (Fe-TiO2) photocatalysts were prepared by a sol-gel method, and the catalyst was immobilized on the surface of a spinning disk reactor (SDR) turntable by a dip-immobilizing method. The synthesized TiO2 film and Fe-TiO2 film were characterized using X-ray diffraction, Raman spectra, ultraviolet and visible spectra and scanning electron microscopy. The results proved that the prepared TiO2 and Fe-TiO2 nanoparticles were anatase phase and the average crystallite sizes were 20 nm and 10 nm, respectively. The effect of rotational speed and flow rate on the photocatalytic efficiency of TiO2 and the degradation performance of phenol wastewater by three systems of TiO2, Fe-TiO2 and TiO2/H2O2 were investigated. The results showed that the rotational speed and flow rate are the main factors a flecting the thickness and residence time of the surface of the turntable, and then the degradation efficiency of phenol wastewater was a flected; in the three catalytic systems, the degradation rate of TiO2 was 41%, Fe-TiO2 increased to 70%, and TiO2/H2O2 reached 99%.
