| 摘 要： | 以无机盐为原料,在遵守热力学限制的前提下,采用室温固相化学反应法合成了复合氧化物CdSnO3,X-射线粉末衍射(XRD)、透射电镜(TEM)等表征结果表明,固相反应完全,产物为β-CdSnO3,其粒径为30 nm左右,与传统方法相比,该法降低了CdSnO3的物相形成温度.气敏性能测试结果表明,以该法合成的CdSnO3为基体的气敏元件,对体积分数0.005%酒精的灵敏度高达63.6倍,抗干扰能力强,响应-恢复快,为应用前景良好的酒敏材料.

| Abstract: | Nanometer CdSnO 3 was synthesized by solid-state reaction with inorganic reagents at room temperature. The results from XRD and TEM indicate that the solid-state reaction is complete and feasible; the mean sizes of the CdSnO 3powders are 30 nm. The gas-sensing measurements results reveal that the sensors based on CdSnO 3 show a high sensitivity and selectivity to ethanol gas. And its sensitivity to 0 005% alcohol gas is up to 63 6 times. Thus, this complex oxide is a promising ethanol-sensing material. |
