FIELD: technological processes.
SUBSTANCE: invention relates to a nanostructured catalyst for production of a synthesis gas by means of carbon-dioxide reforming of methane which contains a complex perovskite-like oxide of gadolinium and cobalt. Process for producing of claimed catalyst comprises production of a complex oxide by solid-phase synthesis from stoichiometric composition of gadolinium oxide Gd2O3 and Co3O4, which comprises heating of compacted mixture at 973 K for 5 hours after stirring Co3O4 and Gd2O3, subsequent reburdening and pressing of powder into tablets and baking them in an air atmosphere with rise in temperature to 1,173 K and holding at this temperature for 5 hours, repeated reburdening and compressing powder into tablets and baking in an air atmosphere with rise in temperature to 1,373 K and holding at this temperature for 30 hours, cooling after annealing.
EFFECT: technical result consists in obtaining a highly-active catalyst providing yield of synthesis gas close to stoichiometric one.
