Claim 11:
12. A method of manufacturing a methane oxidation catalyst, the method comprising:
providing a palladium (Pd)-based catalyst including Pd dispersed onto a support;
introducing a magnesium (Mg) precursor to the Pd-based catalyst by one of ion exchange or incipient wetness impregnation; and
after introducing the magnesium precursor to the Pd-based catalyst, drying the catalyst and subjecting the catalyst to a final heat treatment;
wherein the step of providing a Pd-based catalyst includes introducing a Pd precursor to the support;
wherein the Pd precursor is introduced to the support by one of ion exchange or incipient wetness impregnation;
wherein the Pd precursor and Mg precursor are added sequentially, in that order;
wherein prior to the addition of the Mg precursor, the Pd-based catalyst is subjected to an intermediate heat treatment that is hydrothermal calcination performed at a temperature in the range of 400 to 800° C. for a time period of 4 hours or more in the presence of water, oxygen, and nitrogen.
