Abstract: A catalyst for oxidative coupling of methane, and preparation and application thereof. The catalyst comprises: a manganese sesquioxide, a tungstate, a manganese composite oxide having a perovskite structure and/or a spinel structure, and a carrier. The manganese sesquioxide, tungstate, and manganese composite oxide having a perovskite structure and/or a spinel structure are supported on the carrier, or the manganese sesquioxide and tungstate are supported on the admixture of the said manganese composite oxide having a perovskite structure and/or a spinel structure and the said carrier. Based on 100 parts by weight of the catalyst, the content of the manganese sesquioxide is a parts by weight, the content of the tungstate is b parts by weight, the content of the manganese composite oxide having the perovskite structure and/or the spinel structure is c parts by weight The content of the carrier is d parts by weight. 0<a?20, 1?b?20, 1?c?40, 20?d<98.
