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.
