Catalyst in which a site is doped with ca/sr, a’ site is doped with la/y, and ti site is doped with ru in a perovskite a1-ya’yti1-xruxo3 structure, manufacturing method thereof, and dry reforming method using the same

Abstract

The present application discloses a catalyst with a perovskite structure, a method for preparing the same, and a dry reforming method using the same. The catalyst is represented by A1-yA′yTi1-xRuxO3 and includes Ru nanoparticles exsoluted onto the catalyst surface. In the formula, A is Sr, Ca, or a combination thereof, A′ is La, Y, or a combination thereof, x is greater than 0 and less than or equal to 0.5, and y is greater than 0 and less than 1.0. The catalyst has the effect of maximizing the conversion rates of methane and carbon dioxide by maximizing the active sites for dry reforming reaction as well as thermal stability.
