摘　　要：考察了反应体系中不同制备方法制得催化剂的催化性能，并将分形维数应用于催化剂制备；采用了ＥＤＸ、ＴＰＲ、ＸＲＤ 和ＸＰＳ 等表征手段分析了不同制备方法制得催化剂的表面组成以及还原特性，探讨了层浸法制备的催化剂性能最佳的原因。Catalysts from different preparation methods were studied over their performance and fractional dimension was applied to characterize them The characterization methods of EDX,TPR,XRD and XPS were used to analyze catalyst surface components and their reduction properties The reason why catalyst prepared by layer impregnation showed good performance was explored
