“…As known, methane decomposition on carbon catalysts usually occurs at high reaction temperature of above 750 C [16,23], which inevitable results in the sintering of Ni particles and quick deactivation. Lately, increasing attention has been devoted to the development of iron-based catalysts for their cheaper, non-toxic properties than Ni catalysts [24]. Although Fe-based catalyst has lower catalytic activity than Ni based one at low reaction temperature, it is possible to obtain higher methane conversion on Fe catalyst at high temperatures (above 700 C), because high temperature results in a positive shift in the methane decomposition reaction equilibrium and making full use of the catalytic activity of AC itself as the catalysts.…”

“…Our group has recently synthesized high loaded iron oxide based catalysts with Al 2 O 3 and MgO as textural promoters (Fe/MgO and Fe/Al 2 O 3 ) [14,15,17,18]. These catalysts showed methane conversion values close to equilibrium along with the production of MWCNTs and bamboo CNTs (also named as chain-like type [19]).…”

“…As a result, the probability of reaction (2) proceeding increased following the order: R = H, CH3, C2H5, n-C3H7, and so the Co/B ratio decreased following the same order. Reaction (1) shows that the Co 2+ reduction required the participation of RO -, and higher solvent acidity and lower R group steric hindrance favored reaction (1). This accounts for the Co/B ratio of CoB(MeOH) being larger than that of CoB(H2O).…”
