Atomic Layer Structure of Vanadium Oxide Nanotubes Grown on Nanourchin Structures

Low‐Dimensional, Hinged Bar‐code Metal Oxide Layers and Free‐Standing, Ordered Organic Nanostructures from Turbostratic Vanadium Oxide

“…There is a notable absence of a high intensity (002) reflection from the xerogel diffraction pattern (more observable on the logarithmic scale in Figure 1a) consistent with its arrangement as a double bi-layered product where two vanadate layers are bound by a bi-layered surfactant [7,16] and this arrangement is stacked periodically back-to-back. We also observe similarly low intensities for the {00l} peaks, where l = 2, 4, 6, …, 2(n -1); n ∈ ℵ.…”

“…[16] The values suggest that the intercalated surfactant adopts a tilted bi-layer structure, a well-documented ordering for self-assembled monolayers of thiols. [34,35] X-ray diffraction analysis was also conducted on the nanocomposite after HT.…”

“…Nanostructures with lamellar structure, [8] scrolled nanotubes, [11,12] nanowires, [13] nanorods [14] and nanourchin [15,16] have been realized using a variety of organic templates during synthesis. Each of these structures relies on the structural direction provided by intercalated or adsorbed organic molecules.…”

Reduced Surfactant Uptake in Three Dimensional Assemblies of VOx Nanotubes Improves Reversible Li+ Intercalation and Charge Capacity

“…Vanadium oxide-based low-dimensional products have been studied extensively [11][12][13][14] . Starting from the laminar V 2 O 5 xerogel [15] numerous two dimensional organic-inorganic intercalation products have been obtained [16] . Most nanomaterials offer unusual (different from bulk) properties endowed by confined dimensions, and the overall behaviour can often exhibit a combination of bulk and surface properties [17] .…”

“…Hydrothermal treatment (HT) of laminar composites, either those intercalated with longchained organic molecules or those obtained directly from precursors, results in lowdimensional tubular products with practical quantitative yields [11,16] . Many of these vanadate based nanostructures may be obtained in quantities of the order of grams [18,19] .…”
