The H2/O2 Reaction on a Palladium Model Catalyst Studied with Laser-Induced Fluorescence and Microcalorimetry
Abstract
:Introduction
Methods
Results and Discussion
- The quotient SH2(0)/SO2(0) of the initial sticking coefficients for H2 and O2 can be calculated from the relative hydrogen pressure, αH2, where the production of water reaches a maximum: αH2Omax.
Ratio between initial sticking coefficients for H2 and O2
Reaction Number | Reaction | Preexponential/Sticking Coefficient | Activation Energy (J/Mol) |
---|---|---|---|
S1 | H2→2H(s) | 1.0 (sticking) | |
S2 | 2H(s)→H2 | 4.0*1021 | 41500 |
S3 | O2→2O(s) | 0.8 (sticking) | |
S4 | 2O(s)→O2 | 4.0*1021 | (213000) |
S5 | H(s)+O(s)⇔OH(s) | 4.0*1021 | 79100 |
S6 | H(s)+OH(s)⇔H2O | 4.0*1021 | 59800 |
S7 | OH(s)+OH(s)⇔H2O+O(s) | 4.0*1021 | 59800 |
S8 | OH→OH(s) | 1 (sticking) | |
S9 | OH(s)→OH | 1.0*1013 | (245000) |
S10 | O→O(s) | 1 (sticking) | |
S11 | O(s)→O | 1.0*1013 | (356000) |
S12 | H→H(s) | 1 (sticking) | |
S13 | H(s)→H | 1.0*1013 | (249000) |
