Studies on combustion catalytic activity of some pure and doped lanthanum cobaltites

---

Abstract.
The aim of this work is to compare the catalytic activity of some pure and doped lanthanum cobaltites,
prepared by solution combustion technique, with a Pt/Al2O3 commercial catalyst. As test reaction we
used the combustion of lean methane mixtures. The experimental data evidenced a significantly better
catalytic activity of a cerium-doped lanthanum cobaltite, prepared by using a-alanine as fuel. The
combustion data, for the lean methane mixtures we tested, are well fitted by a first-order kinetic
expression. The calculated activation energy values are in good agreement with the published data.
