Synthesis and Characterization of Nano-pyramid Decorated ZnO Nanowires...

The wide-band gap (3.37 eV) semiconductor ZnO possesses unique physicochemical properties and
has broad applications in electronics, optoelectronics, energy, sensing and catalysis. ZnO
nanostructures such as wires, belts, rings, helixes and other types of structures have been recently
synthesized [1]. The rich family of hierarchical ZnO nano/micro structures not only provides
important applications but also provides a system for studying the fundamental nature of nucleation,
growth and self-assembly of nanocomponents. Synthesis of surface-architectured nanostructures is
critical to developing nanoscale sensors nanocatalysts. We report here our recent progress on
synthesizing nano-pyramid decorated ZnO nanowires.
