Superior catalytic behaviour of Pt-doped Pd catalysts in the complete oxidation of methane at low temperature

Enhanced hydrothermal stability of high performance lean fuel combustion alumina-supported palladium catalyst modified by nickel

“…Unfortunately, neither palladium nor palladium oxide was detected in all of the samples. This is in agreement with the results found by Lapisardi et al [42] and Maione et al [43], in the case of Pd-based catalysts characterized by a Pd loading lower than 2%. Nevertheless, XRD analysis provided valuable information about the nature of different phases present in the catalysts.…”

An Experimental and Kinetic Modelling Study for Methane Oxidation over Pd-based Catalyst: Inhibition by Water

“…Metkar et al [40], found an average washcoat thickness of about 35 μm for a loading of 0.15 g/cm 3 and in addition that doubling the washcoat gave ca double washcoat thickness [41]. Based on these data it was estimated that a monolith of 20 mm in length and 21-22 mm in diameter with a washcoat mass of 500 mg, which is the case of our sample, would yield a washcoat thickness of 15-17 μm.…”

“…High activity in methane oxidation has resulted in the implementation of Pd-containing materials into the aftertreatment systems utilized for the reduction of emissions from natural gas vehicles (NGVs) [1][2][3]. However, the catalytic activity of these systems is decreasing with time-on-stream and significant research has been addressed to understand the mechanism of Pdbased catalyst deactivation during the methane oxidation.…”

Effect of Bimetallic Pt-Rh and Trimetallic Pt-Pd-Rh Catalysts for Low Temperature Catalytic Combustion of Methane

“…Many reports on noble metal catalysts for complete combustion of hydrocarbons are available. [1][2][3][4] Among the noble-metal catalysts, palladium and platinum on various wash coats have been reported as the most active catalysts for methane combustion, due to their high thermal stability, but easily deactivated by sulphur poison. [5][6][7][8][9][10][11] Recent reports portray that bimetallic catalysts exhibit better properties like improved activity, selectivity, and thermal stability than monometallic catalysts.…”
