Photocapacitive CdS/WO nanostructures for solar energy storage.

Through a facile solvothermal procedure, a CdS/WO nanocomposite has been synthesised which exhibits photocapacitive behaviour under white light illumination at a radiant flux density of 99.3 mW cm. Photoelectrochemical experiments were undertaken to examine the self-charging properties of the material and to develop an understanding of the underlying electronic band structure responsible for the phenomenon.

Active removal of waste dye pollutants using TaN/WO nanocomposite fibres.

A scalable solvothermal technique is reported for the synthesis of a photocatalytic composite material consisting of orthorhombic TaN nanoparticles and WO nanowires. Through X-ray diffraction and X-ray photoelectron spectroscopy, the as-grown tungsten(VI) sub-oxide was identified as monoclinic WO. The composite material catalysed the degradation of Rhodamine B at over double the rate of the TaN nanoparticles alone under illumination by white light, and continued to exhibit superior catalytic properties following recycling of the catalysts.

A coumarin based gold(i)-alkynyl complex: a new class of supramolecular hydrogelators.

A phosphine-gold(i)-alkynyl-coumarin complex, [Au{7-(prop-2-ine-1-yloxy)-1-benzopyran-2-one}(DAPTA)] (), was synthesized and the formation of long luminescent fibers in solution was characterized via fluorescence microscopy and dynamic light scattering. The fibers presented strong blue and green luminescence, suggesting that the gold(i) in the complex increased intersystem crossing due to the heavy atom effect, resulting in a significant increase in triplet emission. The X-ray structure of the fibers indicates that both aurophilic, π-π interactions and hydrogen bonding contribute to their formation in aqueous solvents.
