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。
A precursor was made from cerium carbonate,zirconium carbonate,citric acid and nitric acid via hydrothermal method.Two Ce-Zr complex oxides,Ce0.75Zr0.25O2 and Ce0.4Zr0.6O2,were formed after calcination at 600（℃）.Then the above oxides were aged at 980（℃）,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.
