Abstract
Perovskite-type LaCoO3 oxides were prepared using citrate precursor by spray-freezing/freeze-drying. The calcination temperature for a single phase of LaCoO3 could be lowered to 500°C without formation of any other oxides and the product has the highest surface area of 24 m2/g, which has not been reported yet. It was confirmed by IR and TG analyses that the greater amount of citrate existed in the precursor dried by spray-freezing/freeze-drying than by evaporation drying, which contributed to the high surface area and well-crystallized phase of LaCoO3.
