  • Photocatalytic performance and magnetic separation of TiO2

    Apr 05, 2017· Fe is thought to capture electrons that are photo-generated in TiO 2. This promotes the separation of photo-generated electrons and holes, so is responsible for the highest photocatalytic performance. Fe/TiO 2 has the highest saturation magnetization (61.5 emu/g), which is beneficial for magnetic separation. (3)
