| 摘 要： | 以碳酸铈,碳酸锆作为原料,柠檬酸,硝酸作为添加剂,通过水热法制备出前驱物后,将其在600°C下煅烧得到铈锆复合氧化物Ce0.75Zr0.25O2和Ce0.4Zr0.6O2。将上述制备的复合氧化物经过980°C老化后即得到高老化比表面积铈锆复合氧化物,其比表面积为17.6 m2/g和19.0 m2/g。并对其性质进行了表征。

| Abstract: | A precursor was made from cerium carbonate,zirconium carbonate,citric acid and nitric acid via hydrothermal method.Two Ce-Zr complex oxides,Ce_(0.75)Zr_(0.25)O_2 and Ce_(0.4)Zr_(0.6)O_2,were formed after calcination at 600(°C).Then the above oxides were aged at 980(°C),and two high-aging specific surface area Ce-Zr complex oxides were obtained with the specific surface area of 17.6 m~2/g and 19.0 m~2/g,respectively.Moreover,the properties of the products were characterized. |
