Abstract

Crystalline FeAlO3/FeAl2O4 nanonets were synthesized by a modified template-assisted approach using anodic aluminum oxide (AAO) as a reactive and sacrificial template to direct and promote interfacial reaction growth (IRG). The as-prepared nanonets replicate the morphology of the porous AAO template and contain mixed FeAlO3 and FeAl2O4. To extend the applicability of the sacrificial-template-assisted IRG approach, porous anodic titanium oxide (ATO) was used as template in place of AAO, giving rise to Zn2TiO4 nanonet/nanotube and PbTiO3 nanonet/nanotube. These latter products are polycrystalline due to the polycrystalline nature of the ATO template. Growth mechanism for the formation of the Zn2TiO4 and PbTiO3 nanostructures is proposed. The present study shows that the IRG approach can be extended to fabricate patterned complex oxide nanomaterials that may find applications in a wide range of nanotechnologies such as electronics, photonics and spintronics.
