| 摘 要： | 通过两步溶液法在氧化铝陶瓷管上先制备出ZnO纳米棒阵列,再用真空蒸镀法在ZnO纳米棒表面形成一层均匀Au膜,于500℃下热处理得到Au纳米颗粒修饰的ZnO(Au-ZnO)纳米棒阵列体系。通过场发射扫描电子显微镜(FE-SEM)和X射线衍射仪(XRD)对ZnO纳米棒阵列和Au-ZnO纳米复合体系进行表面形貌表征和结构分析。气敏性能测试结果表明,Au-ZnO纳米复合体系在300℃下对1000μL·L-1甲醛的灵敏度为41.5,而在200℃下灵敏度仍能达到10.3,表明可以制备低工作温度下气敏性能良好的甲醛气敏传感器。 |

| Abstract: | zinc oxide nanorods array were synthesized directly via a two-step solution approach,and Au film was then formed on ZnO surface by vacuum evaporation,after annealing at 500℃ for 1h,Au nanoparticle modified ZnO (Au-ZnO)nanorods array was obtained.The morphology and structure of Au-ZnO nanorods array were characterized by field emission scanning electron microscope(FESEM)and X-ray diffraction(XRD).The sensitivity of Au-ZnO nanorods array to 1000μL·L~(-1) formaldehyde is 41.5 at 300℃ and 11 at 200 ℃ respectively,revealing the potential to fabricate low temperature high response formaldehyde gas sensor. |
