Abstract
The present disclosure provides a method for preparing a supported metal alloy catalyst for low temperature engine exhaust oxidation without CO or NO inhibition. The catalyst includes bimetallic PdCu alloy deposited on a SiOsupport using the strong electrostatic adsorption method. The PdCu catalyst may be combined with a traditional PGM-based automotive oxidation catalyst in a series or dual-bed configuration. The first stage of the dual-bed system includes the PdCu catalyst, with the primary role of oxidizing CO at low temperature; the PGM-based catalyst in the second stage then oxidizes NO and hydrocarbons in the absence of any CO-inhibition effects.
