| Outline of Final Research Achievements |
The formation of iron oxide nanostructures using a simple thermal oxidation method was reported. This method enables the large-scale formation of nanostructures in the form of one-dimensional nanowires or two-dimensional nanosheets. By controlling the oxidation parameters such as oxidation time, temperature and introducing water-vapor, the nanoarchitectures formation can be controlled. Using these iron oxide nanostructures, removal of harmful Cr(VI) ions via adsorption process was carried out. The Cr(VI) removal properties and the formation mechanism of the nanostructures are reported.

| Academic Significance and Societal Importance of the Research Achievements |
The findings from this research demonstrated the feasibility to control and form iron oxide nanostructures using a facile water-vapor-assisted thermal oxidation process. The iron oxide nanoarchitectures can be used for an efficient removal of heavy metal Cr (VI) ions through adsorption process.
