Synthesis and characterization of porous TiO2 film decorated with bilayer hematite thin film for effective photocatalytic activity

Abstract

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.
