WHEN A Pt electrode is anodized in acid solutions at a potential of about 1500 mV(nhe), molecular oxygen is evolved on the Pt surface, which is covered with a complete monolayer of adsorbed oxygen. l4 This layer is electronically conducting because it does not thicken with continued polarization .l
The catalytic oxidation of lean CH /O /N mixtures was studied by injecting a stream of the mixture onto a polycrystalline platinum foil whose temperatures could be varied by resistance heating between 300 and 1800 K. Experiments were performed in the stagnation point #ow con"guration under steady-st
