BaTiO3 and PbTiO3 perovskite as catalysts for methane combustion

Abstract

Unsupported and γ-Al 2 O 3 -supported Ba and Pb titanate catalysts were prepared, characterized and studied in the combustion of methane, as a test reaction for VOCs’ catalytic combustion. They present good catalytic activities, and after dispersion (5%) on γ-Al 2 O 3 the specific activity of the supported perovskite phase increased 25 and 30 times, respectively, compared with the unsupported samples. PbTiO 3 /γ-Al 2 O 3 shows the best catalytic properties among the tested samples.
