Studies on combustion catalytic activity of some pure and doped lanthanum cob…

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-a…
