| 摘 要： | 以锌盐和碱为原料,采用水热和溶剂热法合成了三种形貌的氧化锌粉体,利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)和X射线光电子能谱仪(XPS)对产物的结构和形貌及表面化学状态进行了表征,并将粉体制备成厚膜型气敏元件,测试了其对几种还原性气体的气敏性能,结果表明:在工作温度为395℃时,三种形貌氧化锌对相同浓度的同种测试气体的灵敏度大小顺序为:菜花状氧化锌﹥棒状氧化锌﹥六棱柱状氧化锌。并对影响氧化锌材料气敏性的各种因素进行了分析。

| Abstract: | Three morphology zinc oxide powders were synthesized by hydrothermal and solvent-thermal method with zinc salt and alkali as the raw materials. The structure, morphology and surface chemical state of products were characterized by X-ray diffraction（XRD）, scanning electron microscope（SEM） and X-ray photoelectron spectroscopy（XPS）. The gas sensor was prepared from these powders and its gas sensitive properties to several kinds of reducing gas were measured. The results showed that three kinds of zinc oxide powders exhibited different sensitivities to same tested gas of same concentration at 395 ℃ ： cauliflower-like ZnO 〉ZnO nanorods 〉six prismatic ZnO. And the factors for influencting zinc oxide gas sensitivity were analyzed. |
