The present invention relates to a methane oxidation coupling catalyst, a method for producing the same, and an application thereof. The composition of the catalyst includes manganese trioxide, tungstate, manganese composite oxide having a perovskite structure and / or spinel structure, and a carrier, and manganese trioxide and tungstate have a perovskite structure and / or spinel structure. It is supported on a manganese composite oxide and a carrier. In the catalyst, based on 100 parts by weight of the catalyst, the content of manganese trioxide is a part by weight, the content of tungstate is b parts by weight, and a manganese composite oxide having a perovskite structure and / or a spinel structure is contained. When the amount is c parts by weight and the carrier content is d parts by weight, 0 <a ≦ 20, 1 ≦ b ≦ 20, 1 ≦ c ≦ 40, 20 ≦ d <98. When applied to a methane oxidative coupling reaction, the catalyst has excellent low temperature activity and selectivity. [Selection diagram] Figure 1 |
