Abstract

The effects of total substitution of Cobalt (Co) by Titanium (Ti) on the oxygen uptake capacities and oxygen adsorption kinetics of La _0.6Sr_0.4Co_0.2Fe_0.8O_3-d (LSCoF) perovskite-type oxides were investigated by thermal analysis. The novel La_0.6Sr_0.4Ti_0.2Fe_0.8O_3-d (LSTiF) perovskite-type oxides were studied in attempts to obtain higher oxygen sorption capacities. The nature of the transition metals clearly affects the oxygen uptake capacities. In both perovskite-type oxides, an increase of temperature from 700 °C to 900 °C increases the oxygen update capacity but with a substitution of Cobalt by Titanium in LSCoF, the oxygen adsorption capacity decreases to about ~2 ml/g at 900 °C.
