英文摘要：

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.
