Tuning the architecture of MgO nanostructures by chemical vapour transport and condensation

摘要

In this paper, we demonstrate the potential of chemical vapour transport and condensation in tuning the architecture of a series of MgO nanostructures through adjusting experimental parameters. Different oxygen partial pressures lead to corresponding well-faceted nanostructures, such as nanowires, cubes, orthogonally branched structures and 'nanotrees', while nanotubes and 'nanofiowers' were formed through multi-step processes under modified experimental details. The synthesis roadmap may promote the in-depth understanding of the growth kinetics of nanostructures, in vapour routes, and these intriguing nano-architectures may find various applications in nanotechnology.
