报道一种由草酸盐热分解制备大比表面(>100 m~2/g)ceO_2的方法。研究表明,草酸盐的沉淀条件、焙烧温度及焙烧时间对CeO_2的比表面有重要的影响。
A method for the preparation of large surface area (> 100 m ~ 2 / g) ceO2 by oxalate pyrolysis was reported. The results show that the precipitation conditions of oxalate, calcination temperature and calcination time have an important effect on the specific surface of CeO_2.
