Synthesis of Magnetically Recoverable Iron (II, III) Oxide-Titanium Dioxide Particles for Application in Photocatalytic Degradation of Phenol in Aqueous Solution
碩士 === 國立高雄科技大學 === 化學工程與材料工程系 === 107 === In this study, the iron (II, III) oxide was synthesized by co-precipitation method, followed by coating TiO2 photocatalyst on Fe3O4 through the sol-gel method by the hydrolysis of titanium tetra-isopropoxide (TTIP) in the presence of water. Finally, the Fe3...

Finally, the Fe3O4 with attached TiO2 was further treated with a solution with an appropriate amount of TTIP, and then calcined at high temperature to form the uniform core-shell structure of Fe3O4@TiO2. The results indicated that although the Fe3O4@TiO2 exhibited slightly lower degradation performance than the commercial TiO2 (P25) towards phenol in aqueous solution, but it showed much better recovery efficiency (about 96 %) than P25 and P25/Fe3O4 composite through magnetic fields. After the recovery test, the core-shell structure of TiO2@Fe3O4 remained almost unchanged due to the formation protective TiO2 layer on the Fe3O4@TiO2. Wu, Mao-Sung 吳茂松 2019 學位論文 ; thesis 78 zh-TW |
