采用共沉淀法、溶胶-凝胶法和燃烧法制备LaMnO3钙钛矿型催化材料,考察了不同制备方法对催化材料结构和性能的影响。用X射线衍射仪(XRD)﹑比表面测定仪(BET)和扫描电子显微镜(SEM)等分析手段对催化剂的微观结构进行了表征。用催化剂评价系统考察了催化剂对CO的催化氧化活性。
LaMnO3 perovskite catalysts were prepared by coprecipitation, sol-gel and combustion methods. The effects of different preparation methods on the structure and properties of the catalysts were investigated. The microstructure of the catalyst was characterized by X-ray diffraction (XRD), specific surface area (BET) and scanning electron microscopy (SEM). The catalytic activity of the catalyst for CO oxidation was investigated using a catalyst evaluation system.
