Synergistic Effect of Catalyst Basicity and Reducibility on Performance of Ternary CeO2-based Catalyst for CO2 OCM to C2

Abstract:

The present investigation focuses on the synergistic effect of catalyst basicity and reducibility on the catalytic activity of binary and ternary CeO₂-based catalysts in the CO₂ oxidative coupling of methane (CO₂ OCM). Proper amount of medium and strong basic sites together with lower amount of very strong basic sites are identified as pertinent factors in increasing the catalytic performance. The CO₂-TPD and H₂-TPR studies indicate synergistic effect between the catalyst basicity and reducibility for the 12.8CaO–6.4MnO/CeO₂ ternary metal-oxide catalyst in enhancing the CO₂ OCM performance.
