摘要

The whole process of preparing La_0.8Sr_0.2CoO₃ oxide powders by a cellulose adsorption method was investigated by TG, DTA, XRD, and CO₂-TPD techniques. It was found that cellulose first acted as an adsorbent. During the initial stage of pyrolysis, the cellulose was partially oxidized, and some carboxyl groups were formed in the cellulose texture, which was then complexed with the metal ions. At optimized condition, pure phase LSCO powder could be acquired at low temperature. But, if the produced CO₂ could not elute in time, carbonate would form during pyrolysis, and a calcined temperature higher than 800°C was needed.
