| 摘 要： | 用微乳液法制备了表面经十二烷基苯磺酸钠（ＤＢＳ）修饰的ＣｏＯ纳米粒子，初步探讨了合成的最佳条件，利用Ｘ射线衍射仪（ＸＲＤ）、透射电子显微镜（ＴＥＭ）、红外光谱仪（ＩＲ）和Ｘ光能谱仪（ＸＰＳ）研究了样品的性质，并将其用到一氧化碳氧化生成二氧化碳的反应中研究其催化性能。实验结果表明：此法制备的ＣｏＯ纳米粒子呈球状，属立方多晶结构，粒径可以控制，表面活性剂ＤＢＳ以ＳＯ３＾２－形式与Ｃｏ＾２＋相结合。对一

| Abstract: | CoO nanometer particle were prepared by microemusion method.The sample were characterized by XRD,TEM and FTIR.Then,we reaserch the CoO nanometer particle's catatysis for the oxide reation of CO.The result show:the smaller,the CoO nanometer particle size is,the higher the catatyic activity is.The results may be accounted by the size effect and the surface. |

| Keywords: | nanometer particle catalytic activity the effect of surface |
