## Abstract Rare earth (viz. La, Ce, Sm, Nd and Yb) promoted CaO catalysts have been investigated, comparing their surface properties (viz. surface area and basicity/base strength distribution) and catalytic activity/selectivity in the oxidative coupling of methane at different reaction conditions
Deposition of LiΓMgO catalyst on commonly used supports (containing SiC, etc.) causes a drastic reduction in SiO 2 , Al 2 O 3 , ZrO 2 , HfO 2 , the catalytic activity/selectivity for the oxidative methane coupling reaction and also in both the total and strong surface basicity. The decrease in the
