In Situ FTIR Study of Effect of La on CH3OH Automobile Exhaust Oxidation Mechanism on Supported Palladium Catalyst

Abstract

Abstract: The performance of deep oxidation of methanol on 0.1% Pd supported on alumina was studied by a chromatograph-micro-reactor. The results showed that the addition of La intoγ-Al₂O₃ could affect the performance of Pd catalyst greatly. Although the presence of La could not lower the light-off temperature of methanol oxidation, the partial oxidation products disappeared. By usingin-situ FTIR, it is shown that La changed the adsorbed species and the methanol deep oxidation mechanism on Pd catalyst.

Key words: Supported palladium catalyst, Methanol oxidation, Lanthanum, In-situ FTIR
