| 摘 要： | 采用复合碱媒介法(CHM),在合成BaMnO3和Ba0.5Sr0.5MnO3的基础上,以Sr(NO3)2、BaCO3以及MnO2和TiO2为原料,在200℃、24h的生长条件下,用20%的Sr离子替代20%的Ba离子,用50%的Ti离子替代50%的Mn离子成功合成了Ba0.8Sr0.2Ti0.5Mn0.5O3纳米晶体。采用XRD、SEM及EDS对产物的晶相、形貌和成分进行了分析,对Ba0.8Sr0.2Ti0.5Mn0.5O3制作的电极进行了气敏性质的测定。

| Abstract: | Ba0.8Sr0.2Ti0.5Mn0.5O3 nanorods started from Sr(NO3)2,BaCO3,MnO2 and TiO2 were successfully synthesized by a composite-hydroxide-mediated(CHM) method at 200℃ for 24h.Morphology,composition and crystalline phase were investigated by XRD,SEM and EDS.Gas sensitivity was investigated on the Ba0.8Sr0.2Ti0.5Mn0.5O3 nanorods for O2.The results show that the nanorods may be adopted for development of gas sensors with performa-nces suitable for practical applications. |
