Electrochemical route to the synthesis of ultrathin ZnO nanorod/nanobelt arrays on zinc substrate

An electrochemical route has been developed for the synthesis of highly ordered ZnO ultrathin nanorod and hierarchical nanobelt arrays on zinc substrate. A H-2 gas sensor based on the ZnO nanobelt array exhibits excellent sensitivity, rapid response, and good reproducibility even at room temperature. (c) 2007 American Institute of Physics.
