(A) Rate of methane consumption (mol·min−1·kg−1cat) as a function of the amount of surface Ni (mmol), during methane dry reforming. ■: Pure Ni; ▲: Ni/(Ni + Fe) = 0.80; ●: Ni/(Ni + Fe) = 0.75; □: Ni/(Ni + Fe) = 0.5; ∆: Ni/(Ni + Fe) = 0.25 and ○: Pure Fe, all supported on MgxAlyOz and (B) rate of methane consumption (mol·min−1·kg−1cat) as a function of time-on-stream (TOS) during DRM at 923 K.
