A novel route to the formation of 3D nanoflower-like hierarchical iron oxide nanostructure

Abstract: The present work reports the formation of 3D nanoflower-like morphology of iron alkoxide via the anodization of Fe sheet in ethylene glycol (EG) electrolyte. XRD, FESEM, EDX, XPS, Raman and FTIR are applied to characterize the samples. SEM results show that the as-anodized sample is composed of 3D nanoflowers with hierarchical nanosheets beneath it. The average width of the nanoflower petal is ∼25 nm and the length is about 1 μm. The 3D nanoflowers are transformed into spherical nanoparticles (NPs) with unifor… Show more

“…As shown by the EDS results [ Figure 6 (c,d)], the products on the surface were mainly composed of Fe, C, and O, suggesting that the products contained iron oxides. The presence of iron oxides and the observed nanoflower-like morphology were consistent with previous reports, 33,34 indicating that corrosion reactions occurred even with coating protection.…”

“…The SEM images show the specific morphology and three-dimensional structure of the CuFe 2 O 4 @SiO 2 -poly­( m -phenylene terephthalamide) nanocomposite (Figure A–C). Three-dimensional nanoflower morphologies have been reported for metal oxide and metal alkoxide structures such as iron alkoxide , and for gold nanoparticles. Figure A–C shows that a unique nanoflower morphology has been obtained in the present case, which are the results of the formation of nanoplates (see Figure C) with specific orientations.…”

“…10–12 It describes random aggregation of free particles undergoing Brownian motion until they stick irreversibly to the previously formed aggregate. 13–15 Similar non-equilibrium growth processes to DLA occur in the formation of some nanostructures, such as nanoflowers 16–20 and pine-needles. 21–24 However, these processes have clear growth direction due to crystallization.…”
