Fig. 5: Time courses for the oxidation of methane over Ni(5)/MOR-45.
From: Zeolite-supported ultra-small nickel as catalyst for selective oxidation of methane to syngas

a (○) Conversion of methane and selectivities for (△) CO and (∇) CO2. b (○) Yield of H2 and (◊) mol ratio of H2 to CO. Reaction conditions: CH4:O2:Ar = 0.06:0.03:0.91 (atm); total pressure, 0.1 MPa; temperature, 973 K; and SV = 3.0 × 104 mL h−1 g-cat−1. 97–98% methane conversion, 91–92% of CO yield with a H2/CO ratio of 2.0 without serious carbon deposition onto the catalyst.
