摘　　要：利用不同湿化学法制备了具有丰富微观形貌的纳米ZnO,研究了不同制备条件对ZnO形貌的影响,结果表明反应体系过饱和度及压力对所得材料的微观形貌均有较大的影响;系统测试了基于不同微观形貌ZnO气敏元件对丙酮和乙醇气体的敏感性能,结果显示基于棒状连排微观形貌ZnO的气敏元件,其性能最佳。Highly oriented zinc oxide（ZnO） nanoparticles with abundant micromorphologies were synthesized by different wet chemical methods. Effects of the preparation conditions on the ZnO morphologies were investigated. The results show micromorphologies of ZnO are under the influence of degree of supersaturation and pressure. The gas sensing properties of ZnO sensors to acetone and alcohol gas were also studied. It is found that the sensor fabricated by ZnO rows assembled by ZnO nanorods exhibits the best sensing responses to test gases.
