Abstract
The adsorption and catalytic reactions of , CO, and on Pt were investigated with a quartz-crystal microbalance having a sensitivity of ∼ g/ (< monolayers of oxygen). At zero coverage the sticking coefficients for , CO, and were 0.62, 0.54, and 0.38, respectively. The catalytic oxidation reactions all exhibited Langmuir-Hinshelwood behavior. Detailed rate curves were measured for the - reaction. The maximum reaction probability was 0.32 per impinging .
