摘　　要：采用溶胶- 凝胶法合成了样品,通过XRD 分析,确定其为钙钛矿结构,估算了其平均粒度已达到纳米级,并初步进行了CO 催化氧化活性实验。La 1-x Sr x CoO 3 samples were prepared by Sol Gel method. Their structures were identified as perovskites by XRD, and their average particle sizes were nanoparticles. The catalytic activity for monocarbon oxidation over the samples was tentatively tested.
