The turnover rate for the catalytic combustion of methane over palladium is not sensitive to the structure of the catalyst.
The kinetics for the catalytic combustion of methane on Pd in its metal and oxide forms was measured on a foil and on large single crystals exposing initially the (111), (100), and (110) planes. The rates, reaction orders, and activation energies were not dependent on the structure of the active phase. Turnover rates were strictly proportional to the total surface area. The kinetic data were in agreement with the ones for supported catalysts. The values reported can be used as benchmark kinetic values for this reaction since purity and effect of support could be controlled.
