Metallic single-walled carbon nanotubes (SWCNTs) have been regarded as unique quasi-1D metallic systems. Their basic properties significantly differ from those of their semiconducting counterparts even though their chemical compositions and sizes are

Layered tungsten disulfide nanostructures are of both fundamental and technological interest. The widths of currently synthesized WS2 ribbons are in the microscale. By using single-walled carbon nanotubes and double-walled carbon nanotubes as templat

Quasi-one-dimensional nanotubes and two-dimensional nanoribbons are two fundamental forms of nanostructures, and integrating them into a novel mixed low-dimensional nanomaterial is fascinating and challenging. We have synthesized a stable mixed low-d

Band gap photoluminescence (PL) of single-walled carbon nanotubes (SWCNTs) encapsulating C60 fullerenes (nanopeapods) is examined over a wide range of diameters (∼1.25−1.55 nm). The encapsulated fullerenes induce characteristic PL peak shifts tha

We report optical band gap modifications of single-walled carbon nanotubes upon C60 insertions by using photoluminescence and the corresponding excitation spectroscopy. The shifts in optical transition energies strongly depend on the tube diameter (d

Fourier Transform Infrared (FT-IR) spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to investigate the species adsorbed on TiO2 related to photocatalytic activity. Dichloroacetyl chloride (DCAC), which is generated during the photoca

Nitrogen-doped visible light-driven TiO 2 photocatalyst powders were prepared at different temperatures and with different calcination times in a cylindrical tubular furnace under a stream of ammonia gas. Band-gap energy was from 2.92 to 3.04 eV, cor

We observed the chemical adsorption with gas-phase phosgene on TiO 2 surfaces using in situ FT-IR, and examined its effect on the photocatalytic decomposition of trichloroethylene (TCE). The infrared spectrum of the adsorbed standard phosgene suggest

The optical response of single-walled carbon nanotubes (SWCNTs) to far-infrared (FIR) radiation was systematically studied using various SWCNTs with different tube-length distributions. The observed peak position in the FIR spectra linearly scaled wi

Hydrogen gas, which can be used in fuel cells to generate electricity, is considered the ultimate clean energy source. Recently, it was reported that a photo-induced electron transfer system consisting of single-walled carbon nanotubes (SWCNTs) and f
