文摘

The catalytic behaviour of Pt supported on carbon-based monoliths was studied in the low-temperature catalytic combustion of benzene, toluene and m-xylene and compared with the corresponding behaviour of Pt supported on γ-Al₂O₃ coated monoliths. Carbon-based monoliths showed a much better catalytic performance which is ascribed to the fact that the carbon surface is more hydrophobic than the γ-Al₂O₃ one, and the release of water molecules produced during the combustion is favoured.
