One-dimensional (1-D) nanoscale heterostructures

Iron oxides, including α -Fe 2 O 3 , γ -Fe 2 O 3 , Fe 3 O 4 , etc. are one of the most widely investigated materials for their fundamental properties and potential applications. One-dimensional (1-D) iron oxides nanostructures are the focus of recent research activities because of their wide applications in magnetic refrigeration, information storage, electronics, catalysts, Li-ion battery, pigment, gas sensors, etc. This review covers the recent progress in the synthesis, properties and applications of 1-D iron oxides nanostructures. The paper begins with the introduction to 1-D iron oxides nanostructures, followed by the typical synthetic methods developed for the synthesis of 1-D iron oxides nanostructures. Then, the typical 1-D iron oxides nanostructures, including nanowires/nanorods, nanotubes, nanobelts, nanochains, and special 3-D structures built on 1-D building blocks, are introduced in detail. The properties of 1-D iron oxides nanostructures are then discussed, focusing on the magnetic, gas sensing, and electrochemical and photocatalytic properties. Finally, we draw conclusions and look at the prospects of 1-D iron oxides nanostructures.

One-dimensional iron oxides nanostructures

SiO2 nanotubes with tunable diameters and lengths have been successfully synthesized via a simple in situ templatelike process by thermal evaporation of SiO, ZnS, and GaN in a vertical induction furnace. The structure and morphologies were systematically investigated using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray spectrometry. Studies found that both the diameters and lengths of the SiO2 nanotubes can be effectively tuned by simply changing the reaction temperatures. The range of changes was from 30 nm (diameter) and several hundred micrometers (length) at 1450 °C to 100 nm (diameter) and 2−10 micrometers (length) at 1300 °C. Varying some other experimental parameters results in the formation of additional SiO2-based nanostructures, such as core−shell ZnS−SiO2 nanocables, ZnS nanoparticle filled SiO2 nanotubes, and fluffy SiO2 spheres. Based on the observations, an in situ templatelike process was proposed to explain the possible growth...
