CO2 Product Velocity Distribution for CO Oxidation on Platinum.
Abstract
It has been inferred from the very peaked angular distribution of the CO2 formed by catalytic oxidation of CO on Pt(111) that the product CO2 is desorbed with excess translational kinetic energy. The first direct measurement of the CO2 velocity distributions and angular distributions for this reaction on polycrystalline Pt are reported. These qualitatively confirm the inference and give quantitative information. For CO2 desorbing in the normal direction the most probable velocity was 116000 cm/sec, implying a kinetic energy of E/k = 3560 K. At larger angles from the surface normal the most probable velocity decreases monotonically. At 45 degrees it is 90000 cm/sec for a kinetic energy of E/k - 2140 degrees. (Author)
