Considerable research attentions have been paid to one-dimensional (1D) nanostructures, due to their unique properties and applications in optical, electrical, and magnetic devices . In particular, since the discovery of carbon nanotubes , research opportunities have been opened up for a variety of inorganic nanotubes [3, 4, 5]. Much many chemical methods have been reported to reach 1D nanostructures, such as self-assembly of 0D nanostructure , using capping reagents to control and modify the growth habit of a seed . Especially, template-directed synthesis represents an elegant straightforward route to organize 1D nanostructures and to control the size and shape of nanocrystals . Among the various nanoscale materials, nanobelts have also attracted much interest as potential interconnects and active components in fabricating nanoscale electronic and photonic devices .
