| 摘 要： | 在NaC l+KC l熔盐介质中,在660℃下对利用微乳技术制备的前驱物进行焙烧,成功合成了SnO2纳米棒。利用TEM,XRD对SnO2纳米棒形貌、成分进行了表征和分析,SnO2纳米棒直径为10~20 nm,长度从几百个纳米到几个微米。研究表明:以SnO2纳米棒为原料制备的厚膜气敏元件,对乙醇具有较高的灵敏度、好的选择性和响应-恢复特性。 |

| Abstract: | SnO_2 nanorods are prepared by calcinedating precursor powders at 660 ℃ in molten salt medium of NaCl+KCl.The structure and morphology of SnO_2 nanorods is investigated by powder(X-ray) diffraction(XRD)and transmission electron microscopy(TEM).The diameter of SnO_2 nanorods from 10 nanometre to 20 nanometre,length is from several hundreds nanometre to several micron.The gas property of SnO_2 nanorods is studies.The investigation demonstrates that the sensor based on SnO_2 nanorods has higher sensitivity,higher selectivity and better response and reversion character. |
| Keywords: | SnO2 nanorods gas sensing property C2H5OH solid state reaction |
