Hydrocarbon oxidative coupling methods, such as methane oxidative coupling methods, include providing an oxidation catalyst in a reaction vessel and allowing the oxidative coupling reaction to occur under a series of reaction conditions. The oxidation catalyst is (A) at least one element selected from the group consisting of lanthanoid group, Mg, Ca and Group 4 element (Ti, Zr and Hf) of the periodic table, (B) At least one element selected from the group consisting of Group 1 elements Li, Na, K, Rb, Cs and Group 3 elements (including La and Ac) and Group 5-15 elements, (C) 1 It contains at least one element selected from the group consisting of Li, Na, K, Rb, Cs and the elements Ca, Sr and Ba, which are group elements, and (D) oxygen. |
