【摘要】 采用水热合成法制备了球形纳米In₂O₃材料,通过X射线衍射（XRD）和扫描电镜（SEM）对材料进行了表征。将球形In₂O₃与CdO材料按照摩尔比1:1混合制作气敏元件,测试了元件对甲醛气体的敏感性能,元件的最佳工作温度约为170℃。该气敏元件不仅对甲醛的响应高,而且具有选择性好的特点。更多还原

【Abstract】 Nanoball In₂O₃ was synthesized by a hydrothermal process.The powders were characterized by X-ray diffraction（XRD） and scanning electron microscopy（SEM）.The gas sensors based on In₂O₃ mixed with CdO （1:1 in molar ratio） were prepared and the response properties to formaldehyde were investigated,the best working temperature is about 170℃.It was found that the sensors have high response and satisfactory selectivity to formaldehyde.更多还原
