Micelle-mediated synthesis of single-crystalline selenium nanotubes

Large-scale synthesis of single-crystalline selenium nanotubes was carried out by a micelle-mediated solution approach. It was observed that the surfactant concentration plays a key role in the formation of the t-Se nanotubes and 1D t-Se nanostructures other than nanotubes can be obtained at different surfactant concentrations. This low-temperature soft chemical strategy is potentially extendable to other inorganic materials with anisotropic structures. The obtained Se nanotubes was found useful as templates to produce tubular nanostructures of other functional materials.
