Abstract
Iron oxide nanostructure was synthesized on pure Fe foil by thermal oxidation process approach. Conventionally, iron oxide nanostructure can produced by others techniques such as; sol-gel process, template method, thermal decomposition, hydrothermal process and others. However, these technique are costly and complicated. Hence, this project serves to fabricate the iron oxide by using thermal oxidation. Several parameter were investigated such as the effect of oxidation time, oxidation temperature and condition on the substrate. The morphologies and phases of Fe2O3 nanostructure was characterized. The effect of oxidation temperature formed Fe2O3 nanostructure. Several phase oxide were observed such as α-Fe2O3 and Fe3O4. Furthermore, FESEM observation showed the ordered Fe2O3 nanostructure structure was successfully formed on pure Fe foil. XRD and Raman spectroscopy confirmed variant phase: α-Fe2O3 and Fe3O4 occurred after oxidizing. Raman spectroscopy were used to support the morphologies and phases observed by SEM and XRD. While, the optimum sample (oxidized at 400°C, 90min in air ) was subjected to electrochemical characterization in 250ml KOH electrolyte and in photodegradation testing under UV light conditions. The result obtain from this photodegradation shows that, as increase the time of methyl orange solution has changed color, UV visible analysis is used. Based on the results obtained, it can be concluded that the solution was effective degradation process when the time of exposure to light progressively increase.
