摘要：

Well-crystalline ZnO nanorods were synthesized by a simple solution route employing dodecyl benzene sulfonic acid sodium salt (DBS) as a modifying agent. ZnO gas sensors were fabricated from ZnO nanorods with an average diameter of around 95 nm and their gas-sensing properties were investigated. It was found that the sensors based on ZnO nanorods exhibit high responses and good selectivities to benzene and ethanol gas. Our results indicate that ZnO sensors will be promising candidates for practical detectors for dilute benzene and ethanol, respectively. (c) 2006 Elsevier B.V. All rights reserved.
