摘要 采用溶胶凝胶煅烧法合成了La0.5Sr0.5Co0.8Mn0.2O3-δ纳米粉,通过X射线衍射、电子显微镜、X射线光电子能谱和碘定量滴定等测试方法对合成物进行了表征,并以四溴双酚A为模型污染物,考察其催化性能。结果表明,合成的纳米 La0.5Sr0.5Co0.8Mn0.2O3-δ具有钙钛矿R-3c结构,平均晶粒尺寸为40~70 nm。与通氮气煅烧的样品相比,弱氧化煅烧样品的非化学计量氧浓度适中,钙钛矿结构中B位离子平均价态相对较稳定,其催化性能较强且相对较稳定,可再生循环使用四次。

Abstract: The La0.5Sr0.5Co0.8Mn0.2O3-δ nanoparticles were prepared by sol-gel calcinations synthesis. The samples were characterized by means of XRD, electron microscopy, X-ray photoelectron spectroscopy and iodometric titration. Tetrabromobisphenol A was used as model pollutant to investigate its catalytic performance. The results showed that the La0.5Sr0.5Co0.8Mn0.2O3-δ particles had R-3c perovskite structure with an average grain size of 40-70 nm. Compared with the samples calcined under nitrogen, the non-stoichiometric oxygen concentration of the samples calcined by weak oxidation were moderate, the average valence of overall B-site ions in perovskite structure was also relatively stable, and its catalytic performance was therefore strong and relatively stable, which can be recycled for 4 times.
Key words:  nano-scale La0.5Sr0.5Co0.8Mn0.2O3-δ    sol-gel calcinations    non-stoichiometric oxygen    catalytic property
