Transformation mechanism of Te particles into Te nanotubes and nanowires during solvothermal process

Tellurium (Te) nanotubes and nanowires have been controllably and directly transformed from the commercially available Te particles by the solvothermal process in different solvents. X-ray diffraction (XRD) pattern and the selected area electron diffraction (SAED) pattern reveal that the as-synthesized Te nanotubes and nanowires are single crystalline and hexagonal in nature. The morphology evolution of the Te nanostructures along with the reaction time indicates that the formation of Te nanotubes or nanowires resulted from the rolling of Te nanobelt. Moreover, a semi-experimental parameter taking into account the physiochemical properties of solvents, including the surface tension, vapor pressure and Hansen parameters, is presented to judge the formation of Te nanotubes or nanowires.

Fabrication of Nanocables by Electrochemical Deposition Inside Metal Nanotubes

We report a novel route for fabricating Au-Te nanocables. Using nanoporous polycarbonate tract-etching (PCTE) membrane as the template, Au nanotubes were fabricated by electroless Au deposition inside the nanopores of the PCTE membrane. Using the Au nanotube membrane as a second template, Te was deposited on the surfaces of the Au nanotubes by slow electrochemical deposition, taking advantage of underpotential deposition (UPD). The deposition rate was sufficiently slow to radially grow Te nanotubes coaxially within the Au nanotubes to form nanocables.

A self-seeded, surfactant-directed hydrothermal growth of single crystalline lithium manganese oxide nanobelts from the commercial bulky particles.

Single crystalline lithium manganese oxide nanobelts were obtained through a self-seeded, surfactant-directed growth process from the commercial bulky particles under hydrothermal treatment. A possible mechanism was proposed to explain the growth of the nanobelts. This new process could be extended to prepare other one-dimensional nanomaterials such as Se nanorods, Te nanotubes, and MnO2 nanowires.
