Pd-Pt bimetallic catalyst supported on SAPO-5 for catalytic combustion of diluted methane in the presence of water vapor
The examination of the combustion of a trace amount of methane over Pd-ion-exchanged silicoaluminophosphate-5 (Pd-SAPO-5) at low temperature in the presence of water vapor reveals that water vapor strongly depresses methane combustion and causes a significant decrease in catalytic activity with time. The newly prepared bimetallic catalyst Pd-Pt-SAPO-5, on the other hand, shows higher performance for methane combustion under similar conditions.
