英文摘要: The whole process of preparing La0.8Sr0.2CoO3 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 degrees C was needed.
