Partial oxidation of methane (POM) co-fed with CO₂ to syngas in a novel catalytic BaCo_0.6Fe_0.2Ta_0.2O_3-δ oxygen permeable membrane reactor was successfully reported. Adding CO₂ to the partial oxidation of methane reaction not only alters the ratio of CO/H₂, but also increases the oxygen permeation flux and CH₄ conversion. Around 96% CH₄ conversion with more than 93% CO₂ conversion and 100% CO selectivity is achieved, which shows an excellent reaction performance. A steady oxygen permeation flux of 15 mL/ (cm² min) is obtained during the 100-h operation, which shows good stability as well.
