- Summary:
- Significant progress has been achieved in a number of areas with the support of this Department of Energy grant which began on July 1, 1989. We have quantified experimentally the kinetics of the initial (low-coverage) alkane activation reaction, i.e., alkane → alkyl + hydrogen adatom, for the following systems: (1) C₂H₆ on Ir(110)-(1×2), and (2) CH₄, CD₄, C₂H₆ and C₂D₆ on Pt(110)-(1×2). In addition, we have employed dynamic Monte Carlo simulations to study two important aspects of surface reactivity, namely, reactant segregation during a steady-state surface reaction, and the compensation effect in a transient surface reaction. Experimentally determined values of the initial adsorption probability of ethane on Ir(110)(1×2) were employed to probe the dynamics of the interaction. Experimentally determined values of the initial trapping probability ζ₀ of ethane into a physically adsorbed state at T{sub s} = 77 K as a function of E{sub i} and Θ{sub i} and experimentally determined values of the initial probability of dissociative chemisorption P{sub r} as a function of E{sub i}, Θ{sub i} and T{sub s} were obtained.
