Synthesis and Characterization of Nano-pyramid Decorated ZnO Nanowires

Abstract

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.
