From: Atomically dispersed MoNi alloy catalyst for partial oxidation of methane
a CH4-TPSR for pure Ni/SBA-15 and (b) AD MoNi alloy/SBA-15 catalyst. c Reaction order for CH4 and (d) O2. e Phase diagram for AD MoNi alloy with practical O2 partial pressure of ~12.5 kPa under reaction condition at 800 °C. f Possible structure of phase diagram in (e). Red square in (e) and (f) represents real structure according to calculated phase diagram. Ni: blue ball; Mo: bright red ball; O: deep red ball. 5Ni1Mo represents NiMo alloy with Ni:Mo ratio of 5:1 and AD MoNi alloy represents atomically dispersed MoNi alloy.
