Preparation and photocatalytic property of Fe-doped TiO2 micron zonal material

Combining the template method and sol-gel method, the Fe3+ doped TiO2 micron zonal photocatalysis material was synthesized by a cotton template. The surface morphology and crystal features of the samples obtained by different Fe3+ doping proportions were characterized by FTIR, SEM and X-ray diffractometry. By the methylene orange degradation as a model reaction, the photocatalytic property of the TiO2 micron zonal material was investigated. The results indicated that the zonal material was synthesized. The breadth was between 5 and 8 μm, and the wall thickness was between 100 and 500 nm. As the Fe3+ doping proportion was 0.04%, the photocatalysis efficiency was at the maximum. And the photocatalysis efficiency on the methylene orange within 20 min was up to 91% under the optimum doping proportion.
