What is A α-Fe2O3/rGO magnetic photocatalyst: Enhanced photocatalytic performance regulated by magnetic field about?
The magnetic photocatalyst a-Fe 2 O 3 /reduced graphene oxide (rGO) was constructed to enhance the photocatalytic efficiency by the magnetic field. The results of X-ray diffraction spectrometer (XRD), Raman and high resolution transmission electron microscope (HRTEM) indicated the successful preparation of the a-Fe 2 O 3 /rGO composite photocatalyst, and the enhanced optical absorption for visible light after the growth of rGO was also demonstrated by UVevis spectrophotometer. The introduction of rGO enhances the transfer of photogenerated carriers, and the interface effect between a-Fe 2 O 3 and rGO makes the photocatalyst having a stronger magnetization intensity and larger negative magnetoresistance (MR) than pure a-Fe 2 O 3 , thus the introduction of magnetic field can further improve the transfer of carriers. When the mass ratio of a-Fe 2 O 3 and rGO was 10:1, the a-Fe 2 O 3 /rGO composite photocatalyst could reach the best photocatalytic performance, i.e. degrading 60% of Congo red (CR) after visible light irradiation of 30 min, and its photocatalytic performance was much better than that of other photocatalysts with different rGO concentration. With the magnetic field of 100
