Abstract: In experiments on 2 H₂ + O₂ ignition over Pd and Pt foils at P₀ = 40–180 Torr and T₀ = 20–288 °C, it has been shown that the temperature of the initiated ignition over heated Pd foil is ~100 °C lower than that over heated Pt foil; even the minimum temperature is already enough to ignite the mixture. The activity of Pd foil expresses itself both in the dark catalytic reaction and in the occurrence of local ignition centers on the foil, from which combustion wave propagates.
