| 摘 要： | 以柠檬酸为络合剂、PEG为分散剂,用Ce（NO3）3.6H2O和Zr（NO3）4.5H2O为原料制备出CexZr1-xO2。以Mg（NO3）2.6H2O和Al（NO3）3.9H2O为原料,同样方法制得了MgO-Al2O3。进行了X-射线衍射（XRD）和比表面积测试。Scherrer方程计算出MgAl2O4的主要晶面尺寸,表明MgO-Al2O3为纳米粒子。讨论了制备MgO-Al2O3过程中PEG种类和焙烧温度对产物结构的影响。

| Abstract: | A series of CexZr1-xO2 was prepared by citric acid sol-gel method using inorganic salts in the presence of PEG,and MgO-Al2O3 was also obtained in the same way.The products were characterized by using XRD technique and BET surface area measurement.It is revealed that the MgAl2O4 particle size is in the range of nano-meter from the crystallite size data calculated by Scherrer equation.The effect of PEG and calcination temperature on the structure of resulting products was investigated,and the result shows a s... |
