    Abstract

    Heterostructural nanochains consisting of crystalline spinel MgAl 2O4 "nanowires" and amorphous compound oxide "nanobeads" have been synthesized via a simple chemical vapor deposition process. Introduction of methanol is found to play a key role in the generation of the chainlike structure. The regularly spaced nanobeads are obtained on the surface of the spinel nanowires with the introduction of methanol, while only random nanoparticles are observed on the nanowires without methanol. A two-step self-organizing growth model has been proposed. Deep understanding of this distinct chainlike heterostructure is expected to promote the development of novel electrical, optical, and selective catalytic nanodevices. © 2008 American Chemical Society.
