Title
Synergistic effect of Pd in methane combustion PdMnOx/Al2O3 catalysts
Abstract

The catalytic methane combustion was investigated over alumina-supported monometallic and bimetallic palladium and manganese oxide catalysts. The catalytic activity of these systems showed that palladium incorporation on MnOx/Al2O3 catalyst leads to an enhancement in methane combustion. The higher catalytic activity of the PdMn/Al2O3 catalysts is related to a greater mobility of lattice oxygen in manganese oxide in the presence of palladium. These bimetallic catalysts also showed a significant improvement in catalysts stability with respect the monometallic ones. Surface analysis of the used catalysts revealed less amount of coke and Mn/Al and Pd/Al atomic ratios almost unchanged, which is indication of absence of active phase sintering.
