“…Considering all catalyst compositions tested for destruction of these three OVs, activity' for complete OV combustion generally decreased in the order of l-butanol>MEK> toluene. A similar trend also Was observed in the literature, and correlated with dissociation energies of the weakest C-H bond and surface adsorption affinity (Batiot and Hodnett 1996;O'Malley and Hodnett i 997, 1999). However, the compositions with the best performance for 1-butanol destruction were different than those with the best performance for toluene destruction.…”

“…However, the mechanism for oxidation of OVs is different than for CO. The advantages gained by small Au and Pt clusters for CO oxidation are attributed to enhanced dissociation of 0 2 (Haruta et al 1993;Haruta 1997;Valden et al 1998;Heiz et al 1999), which does not appear to be the limiting process for OV oxidation (Batiot and Hodnett 1996;Hodnett 1997, 1999). Whether simply increasing the number of active sites or creating electronic interactions, the challenge for synthesizing these catalysts will be attaining high dispersions of active metals using practical preparation methods.…”

“…It is worth remembering that our target of ~30 % OCM yield approximately corresponds to a kB-to-kA ratio of unity. Figure 6 shows selectivity-conversion plots for the catalytic results found in the literature for the Mn/Na2WO4/SiO2 catalyst (open circles) 52) and for other reported catalysts, such as Li/MgO, Mo-based oxides, Sm2O3 and La2O3 (closed circles 50) , and closed diamond 53) ). The dotted lines in Fig.…”

“…9,11 As a result, the relative rates of these reactions and the concomitant attainable maximum C 2 yields are essentially dictated by the relative C-H bond energies among the hydrocarbons involved in OCM. 17 We report here rigorous kinetic and isotopic assessments of primary and secondary OCM pathways and their elementary steps. We also provide evidence for previously unrecognized effects of H 2 O on the relative rates of these steps and confirm the kinetic irrelevance of the other OCM products (C 2 H 6 , C 2 H 4 , CO x ) in C-H bond activation of CH 4 reactants.…”
