【摘要】 采用两步化学溶液法制备了ZnO和Al-ZnO纳米棒,利用扫描电子显微镜(FE-SEM)(JSM-6700F,Japan)和X射线衍射仪(XRD)(Rigaku D/Max 2500PC,Japan)进行表面形貌表征和结构分析.气敏测试结果表明,Al-ZnO纳米棒元件在380℃下对500和2 000×10-6液化石油气(LPG)的灵敏度分别为9.5和21,掺杂Al3+能有效提高ZnO纳米阵列元件对LPG的气敏性能.更多还原

【Abstract】 ZnO and Al-ZnO nanorods array were synthesized via a two-step solution approach.The morphology and structure of ZnO and Al-ZnO nanorods array were characterized by scanning electron microscope(SEM)(JSM-6700F,Japan) and X-ray diffraction(XRD)(Rigaku D/Max 2 500PC,Japan).The result demonstrated that the sensitivity of Al-ZnO nanorods array was about 9.5 for 500 ppm and 21 for 2 000×10-6 Liquefied Petroleum Gas(LPG)at 380 ℃,respectively.The LPG sensing properties of ZnO nanorods array are improved by doping Al3+.更多还原
