Hydrothermal synthesis of hematite nanoparticles doped with (Ti and Sn) and deposition on FTO
In this study, hematite nanoparticles and hematite nanoparticles doped with Ti, Sn doped have been synthesized and deposited on FTO glass for photo anode application. To make a thin layer of hematite by hydrothermal method, ammonia and ferric chloride solution react indirectly at 120 ̊C for 24 h for better adhesion of synthesized iron hydroxide on FTO glass. The synthesized samples were calcined at 550o C. XRD analysis was confirmed that FeOOH-coated were subsequently converted to the rhombohedral structure of the a-Fe2O3. A complete synthesis study was performed using FTIR analysis and using UV-Vis results, the bandgap energy of the samples was calculated with and without the additive. The finite structure and morphology of synthesized powders were also compared with FESEM images. The results showed that the addition of 1% wt of titanium caused the synthesis of uniform spherical nanoparticles leads to alow electrons bandgap energy of 1.85 eV.
