Abstract: The present disclosure relates to a catalyst for oxidative coupling of methane, specifically, it relates to a catalyst for oxidative coupling of methane comprising: a magnesium titanium oxide support comprising a mixed oxide of magnesium and titanium; and sodium tungstate and manganese oxide supported on the support, a method for preparing the same, and a method for oxidative coupling of methane. The catalyst for oxidative coupling according to the present disclosure, wherein a mixed oxide of magnesium and titanium is used as the support of the catalyst, is capable of providing significantly improved catalytic activity and C2 hydrocarbon yield as compared to pure magnesium oxide or titanium oxide. By preparing the oxide support not by a physical process but by a chemical sol-gel process, a catalyst for oxidative coupling with a peculiar crystal structure not found in a single oxide support can be provided.

Abstract: Provided is a palladium on carbon (Pd/C) catalyst obtained by using an ionic liquid, a method for preparing the same, and a method for hydrogenation of hydrofluorocarbon using the same. More particularly, palladium particles are supported on carbon particles by using an ionic liquid, and the resultant Pd/C catalyst is used for hydrogenation of hydrofluorocarbon. The catalyst includes palladium particles having a smaller particle size and a more uniform shape as compared to the existing Pd/C catalysts, and thus shows high catalytic activity.
