Abstract

Perovskite-type LaCoO₃ oxides were prepared by spray-freezing/freeze-drying method using citrate precursor. The calcination temperature for a single phase of LaCoO₃ could be lowered to 500 °C without formation of any other oxides and the product had the highest surface area of 23.7 m²/g. Below 500 °C, this catalyst with the perovskite structure and the high surface area showed higher activity for complete oxidation of low concentration methane (2000 ppm) and CO (1%) compared to Pt/Al₂O₃ catalyst.
