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

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.

Automated summary

In this study, porous TiO2 films decorated with bilayer hematite (nanoparticles/nanorods) were successfully synthesized using electrodeposition and hydrothermal treatment. XRD, EDS, and SEM were used to investigate the structural and morphological properties of the TiO2/bilayer hematite films. The TiO2/bilayer hematite film showed significant photodegradation of organic dyes under visible light and normal pH, due to its high specific surface area and stability.
