FIELD: chemistry.
SUBSTANCE: invention relates to a material with a perovskite structure, which can be used in methane reforming to produce synthesis gas, hydrogen, complete combustion of methane to carbon dioxide and water. Oxygen-accumulating material based on a complex manganite of a rare-earth element and barium contains neodymium as a rare-earth element, additionally doped with Ca+2 ions and has a composition NdBa0.8Ca0.2Mn2O6-δ.
EFFECT: invention enables to obtain an oxygen-accumulating material which ensures the absence of oxygen capacity degradation during redox cycles, wherein the oxygen capacity reaches 3_65-3_75 wt %.
