Large-area Sb2Te3 nanowire arrays

High-density large-area nanowire arrays of thermoelectric material Sb 2Te3 have been successfully prepared using electrochemical deposition into the channels of the porous anodic alumina membrane. The morphologies, structure, and composition of the as-prepared Sb2Te3 nanowires have been characterized using field-emission scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Individual Sb2Te3 nanowires are single crystalline and continuous with uniform diameters (a??50 nm) throughout the entire length. The atomic ratio of Sb to Te is very close to the 2:3 stoichiometry.

Transitions in order and molecularity with temperature in gaseous metal oxidation reactions. The Sb-O2 system

Examples of reactions which are termolecular near room temperature and gradually switch over to complex-forming bimolecular reactions with increasing temperature are discussed. The Sb/O2 system, which is known from D. Husain's work to be termolecular at 300 K, has been studied here from 1165-1495 K at 12 to 52 mbar in a high-temperature fast-flow reactor (HTFFR). Sb was vaporized from a crucible and atomic resonance absorption spectrometry was used to measure the rates of Sb consumption. Under these conditions the reaction, identified as Sb + O2 → SbO + O, is pressure-independent with k(T) = 6.3×10-11 exp (-9107 K/T) cm3 molecule-1 s-1. The 2σ precision limits are ±8% and the corresponding estimated accuracy limits are ±24%. The results suggest that Do(Sb-O) = 444±28 kJ mol-1. The results are compared to those of other endothermic metal-atom O2 abstraction reactions, all of which have pre-exponentials on the order of 10-10 cm3 molecule-1 s-1 and activation energies for abstraction close to the endothermicity. This allows assessments of the relative importance of bi-, and ter- molecular kinetics, as illustrated for As + O2. by Oldenbourg Wissenschaftsverlag, Muenchen.
