| description | The invention relates to a preparation method of an oxygen carrier for hydrogen production by low-temperature methane oxidation and application of the oxygen carrier, and belongs to the field of methane low-temperature catalysis. Magnesium oxide is prepared by adopting a homogeneous precipitation method and a high-temperature calcination method; magnesium oxide and copper salt are mixed and modified, and the composite CuMgO oxygen carrier is obtained. The preparation method of the oxygen carrier is simple, the oxygen carrier can be used in a low-temperature range, and the recycling efficiency is good. The catalyst can efficiently convert methane into hydrogen at low temperature by using lattice oxygen of the catalyst, the hydrogen selectivity is greater than 97%, and the catalyst can be regenerated in a carbon dioxide atmosphere. After a plurality of circular reactions for a long time, the oxygen carrier can still convert methane into hydrogen, and stable hydrogen production selectivity is maintained. The oxy |
