A coaxial nanohybrid consisting of a single-walled carbon nanotube (SWCNT), fullerodendron, and SiO(2) shows high-efficiency light-driven hydrogen evolution from water. Upon visible light irradiation, SWCNT/fullerodendron/SiO(2) coaxial nanohybrid shows hydrogen evolution activity in the presence of methyl viologen (MV(2+)), benzyldihydronicotinamide (BNAH), and a colloidal polyvinyl alcohol(PVA)-Pt.

Calcium carbonate (CaCO 3 ) in the presence of single-walled carbon nanotube (SWCNT) /fullerodendron supramolecular nanocomposites was crystallized with a CO 2 diffusion method under ambient conditions and in aqueous environments to produce monodisperse spherical SWCNT/CaCO 3 hybrids with a core-shell structure. The crystals nucleate at the carboxyl groups on the surface of the SWCNT/fullerodendron supramolecular nanocomposites grow around a spherical scaffold consisting of the SWCNTs, and finally form spherical calcite crystals embedded with and covered by the SWCNTs. Owing to of the phase transition from vaterite to calcite through a solvent-mediated process, the morphology of the microspheres is unique; the shell is primarily composed of calcite crystals of CaCO 3 , and a greater amount of SWCNTs is embedded in the core moiety.

A coaxial nanohybrid consisting of a single-walled carbon nanotube (SWCNT), fullerodendron, and SiO 2 is created from a bottom-up approach by Yutaka Takaguchi and co-workers and shown to act as a photocatalyst, as reported on page 5750. The SWCNT/fullerodendron/SiO 2 coaxial nanohybrid demonstrates highly effi cient hydrogen evolution from water upon visible-light irradiation in the presence of methyl viologen, benzyldihydronicotinamide, and a colloidal polyvinyl alcohol-Pt.
