Abstract
[Display omitted]
•Fe2O3 was successfully deposited onto porous TiO2 by simple and developed electrochemicaltechnique.•TiO2/bilayer hematite film has good stability and the high specific surface area.•The as-prepared porous photocatalysts Fe2O3 /TiO2 show high visible light photoactivities for the degradation of the methylene blue dye.
In this work, porous TiO2 film decorated with bilayer hematite (nanoparticles/nanorods) were synthesized via the electrodeposition technique followed by hydrothermal treatment. Structural and morphological properties of the TiO2/bilayer hematite films were determined by X-ray diffraction (XRD), Also with energy dispersive X-ray spectral (EDS), and scanning electron microscopy (SEM). Due to its good stability and the high specific surface area, TiO2/bilayer hematite film, as a potential absorber film, can be applied to enhance organic dye degradation. The photodegradation of the porous, thin film trijunction was remarkable under visible light and normal pH.
