Sb-doped ZnO Nanoparticles Prepared by Vapor-phase Oxidation

Abstract

Abstract: Pure and Sb-doped ZnO nanoparticles were obtained by vapor-phase oxidation from Zn-Sb
alloy with different mole ratios as the raw material at the same experimental condition. The morphology, structure and chemical
state were investigated by TEM, XRD, HRTEM and XPS. With an increase in content of Sb in raw materials, the shape of nanoparticles varying
from tetrapod-shaped whisker, rod-liked, quadrangle to hexagon was observed by TEM. HRTEM image of the regularly hexagonal nanoparticles
indicates the distance between (1100) planes neighbouring in the Sb-doped ZnO nanoparticles with wurtzite structure is larger than that of the undoped
ZnO nanoparticles reported in literature. The XPS result clearly shows that Sb element has been doped into the ZnO nanoparticles, although the
XRD patterns of the as-synthesized nanoparticles reveal that there is not second phase except ZnO. The forming mechanism of tetrapod-shaped ZnO
nanoparticles and the effects of Sb on morphology of nanoparticles were discussed.

Key words: vapor-phase oxidation, Sb-doped, ZnO, tetrapod-shaped nano-whisker
