InAlO 3 (ZnO) m superlattice nanowires are successfully synthesized via chemical vapor deposition, using Au catalyst. High-resolution transmission electron microscopy observations indicate that these nanowires consist of an alternative stacking of InO 2 layers and AlO(ZnO) m + blocks along the [0001] direction. The periodicity of these nanowires is proportional to their diameter, which is determined by the Au alloy particle size at the tip of the nanowire. The linear relationship between the periodicity and the diameter is well explained by a cylindrical configuration model. Our results indicate that controlled synthesis of InAlO 3 (ZnO) m superlattice nanowires becomes possible. The photoluminescence properties of InAlO 3 (ZnO) m superlattice nanowires were studied.

Hierarchical ZnCo2O4/Ni(OH)2 nanostructures were rationally designed and successfully fabricated. They show excellent electrochemical performances.

Based on the Mott–Schottky theory, the electron concentration of the as-synthesized nanostructures can be calculated by M–S plot.
