Abstract: Perovskite-type complex oxides GdFeO3 and GdCo0.5Fe0.5O3 synthesized by the sol–gel method and gadolinium ferrite modified with cobalt oxide (5 wt %) are studied as catalysts for the dry reforming of methane. Single-phase catalysts with the perovskite orthorhombic crystal structure and an average particle size of 100–200 nm are synthesized. Catalytic activity testing shows that the surface modification of gadolinium ferrite with cobalt, as well as the introduction of Co directly into the crystal structure to form a GdCo0.5Fe0.5O3 solid solution, leads to the formation of new catalytically active sites and provides an increase in the activity of GdFeO3. The sample with cobalt oxide deposited on the surface is highly resistant to coking.
