Abstract:
Single-crystal gibbsite nanorods with a high aspect ratio were synthesized by a facile hydrothermal method.
Characterizations by HRTEM, SAED, and XRD revealed that the nanorods prefer to grow along the c-axis.
The nanorods can be easily transformed to 
-alumina by calcination at 250 
C, while the nanorod morphology
is well-maintained. HRTEM indicates that the -alumina nanorod possesses a single-crystal-like structure
formed by orientated connection of crystalline nanodomains. Altering the synthetic procedure will lead to
alumina nanostructures with a different phase structure and morphology, such as alumina nanotubes.
