Methane Dissociation and Syngas Formation on Ru, Os, Rh, Ir, Pd, Pt, Cu, Ag, and Au: A Theoretical Study

Oxidation and reforming reactions of CH4 on a stepped Pt(557) single crystal

“…Partial pressure dependencies for both reforming co-reactants are compiled in Table 1. The zero order dependence on methane suggests that surface is covered with C and CH x fragments formed through the sequential dehydrogenation of methane [44]. The measured kinetic dependencies suggest that the large coverage of methane derived species influences the adsorption of both CO 2 and H 2 O to the same extent; both co-reactants display first order behavior.…”

Non-stationary catalytic cracking of methane over ceria-based catalysts: Mechanistic approach and catalyst optimization

“…Among the transition metals, the noble metals can be ranked according the required energy for methane dissociation, based on the theoretical calculation reported by Au et al [17] (Fig. 4).…”

The structural and electronic properties of small osmium clusters (2–14): A density functional theory study

“…[13] Other previous studies demonstrate that Os clusters are effective catalysts for methane dissociation. [14] Recent, it has also been reported that small Os clusters are extremely reactive with single-walled carbon nanotube in comparison to other transition metal clusters. [15] Further research has demonstrated that small Os clusters can be inserted into singlewalled carbon nanotubes, which not only stabilize the Os clusters under ambient conditions but also keeps osmium's catalytic activity without being diminished.…”

“…[12,5] Small Os clusters have also been reported to be good catalysts in many applications due to their unusual chemistry. [13,14,15] For instance, Os 3 helps carbon-carbon bond cleavage and leads to ring opening reaction during the cyclic carbon compounds reactions. [13] Other previous studies demonstrate that Os clusters are effective catalysts for methane dissociation.…”
