A tellurium-substituted Lindqvist-type polyoxoniobate showing high H2evolution catalyzed by tellurium nanowires via photodecomposition

A tellurium-substituted Lindqvist-type polyoxoniobate showing high H(2) evolution catalyzed by tellurium nanowires via photodecomposition.

A new tellurium-substituted Lindqvist-type polyoxoniobate [H2TeNb5O19](5-) was synthesized as a tetramethylammonium salt. When irradiated with a Xe lamp, a water-methanol solution of this cluster showed exceptionally high H2-evolution activity suggesting cocatalysis by the hexaniobate cluster and metallic tellurium, both of which are formed as photodecomposition products.

Pt3Te4 nanoparticles from tellurium nanowires.

We report the synthesis of platinum telluride nanoparticles (Pt(3)Te(4) NPs) in the solution phase at room temperature using a template-assisted method. The dendrimeric aggregates formed are composed of several small units of Pt(3)Te(4) NPs of ∼4 nm diameter. Tellurium nanowires (Te NWs) are used as the template and the reducing agent in the growth of NPs which occurs due to the galvanic replac...

Tellurium and tellurium compounds

Bending and Shell Formation of Tellurium Nanowires Induced by Thiols

The reactivity of tellurium nanowires (Te NWs) with thiol-containing molecules was probed. Depending upon the presence or absence of the stabilizing surfactant in the solution, the product differs drastically. When excess surfactant was present, the reaction resulted in a core-shell-like structure. Through various spectroscopic andmicroscopic techniques, it was understood that there is a redox ...

Tellurium as a high-performance elemental thermoelectric

High-efficiency thermoelectric materials require a high conductivity. It is known that a large number of degenerate band valleys offers many conducting channels for improving the conductivity without detrimental effects on the other properties explicitly, and therefore, increases thermoelectric performance. In addition to the strategy of converging different bands, many semiconductors provide a...
