Dispersion behaviors of molybdena on titania (rutile and/or anatase)

Article Abstract:

The dispersion of molybdena on mixed TiO(sub 2) (rutile and anatase) with different BET surface ratios were investigated with Raman and FT-IR spectra. The results of this investigation show the interaction between OH groups of molybdena and the OH groups of rutile and anatase, and suggests that the different states of the dispersed molybdena result from the different dehydration orders of OH groups of the molybdena and surface OH groups of rutile and anatase.

Synergism of [C.sub.5]N six-membered ring and vapor-liquid-solid growth of C[N.sub.x] nanotubes with pyridine precursor

Article Abstract:

A synergism mechanism of [C.sub.5]N-six-membered-ring-based growth through surface diffusion and vapor-liquid-solid (VLS) growth through bulk diffusion is described. This mechanism can be used to explain the growth phenomena of a series of bamboo-like C[N.sub.x] nanotubes.

Growth of ZnO nanostructures with different morphologies by using hydrothermal technique

Article Abstract:

ZnO nanostructures, including nanotowers, nanovolcanoes, nanorods, nanotubes, and nanoflowers is grown by using the hydrothermal technique. Most of the ZnO nanostructures reveal the perfect hexagonal cross section and well-faceted top and side surfaces.
