Incorporating a TiOx shell in single-walled carbon nanotube/fullerodendron coaxial nanowires: increasing the photocatalytic evolution of H2 from water under irradiation with visible light
A custom-tailored single-walled carbon nanotube (SWCNT) photocatalyst with an electron-extracting TiOx shell, i.e., a SWCNT/fullerodendron/TiOx coaxial nanowire, has been fabricated. Due to the presence of the TiOx shell, the SWCNT/fullerodendron/TiOx coaxial nanowire shows enhanced photocatalytic activity (Φ = 0.47) for the evolution of hydrogen from water under irradiation with visible light (λ = 450 nm).
Ligand Exchange Reaction of (Me4N)4[Cd10S4(SPh)16] with Diphenyl Diselenide
The reaction of (Me4N)4[Cd10S4(SPh)16] (with diphenyl diselenide in propionitrile afforded a molecular cluster, (Me4N)4[Cd10S4(SPh)16], the structure of which was determined by X-ray crystallography. Ligand exchange proceeded in a heterogeneous reaction system, and the use of a less polar solvent appeared to be crucial for the synthesis of (Me4N)4[Cd10S4(SPh)16] to prevent degradation of the Cd10S4(SPh)16 cluster core.
