| 摘 要： | 分别用成核/晶化隔离法和化学共沉淀法制备了ZnO纳米颗粒。用XRD、DSC-TGA表征其微结构和成相温度,静态配气法研究两种方法所制备ZnO纳米颗粒的气敏性能差异。结果表明:成核/晶化隔离法所制备的ZnO纳米颗粒相对于化学共沉淀法制备的ZnO纳米颗粒对酒精和汽油具有更好的气敏性能。290℃工作温度下,成核/晶化隔离法制备的ZnO纳米颗粒对体积分数均为50×10–6的酒精和汽油灵敏度分别高达34和68,远高于化学共沉淀法制备的ZnO纳米颗粒的17和28。

| Abstract: | The ZnO nanoparticles were prepared by methods of nucleation/crystallization separation and chemical coprecipitation. The microstructure and formed phase temperature of the particles were researched by X-ray diffraction (XRD) and DSC-TGA. Gas sensing propertie differences of ZnO nanoparticles prepared by two kinds of methods were measured by a stationary state gas distribution method. The results show that the ZnO nanoparticles prepared by nucleation/crystallization separation method has higher sensitivity ... |
