Abstract
A method for generating carbon monoxide includes: a generation step of generating carbon monoxide by supplying carbon dioxide to a first material containing a first element included in elements of group 11 and a second element included in elements of groups 8 to 10, 12, and 13; and a reduction step of reducing the second element oxidized in the generation step by supplying hydrogen to a second material containing the oxidized second element and the first element. The generation step and the reduction step are repeated a plurality of times.
Claims4
A method for generating carbon monoxide, the method comprising:
- a first reduction step of generating water and a first material containing copper and indium by supplying hydrogen to a precursor that is a composite oxide containing Cu2In2O5, thereby reducing the precursor;
- a generation step of generating carbon monoxide by supplying carbon dioxide to the first material and generating a second material by oxidizing the indium;
- and
- a second reduction step of generating the first material by reducing the indium oxidized by supplying hydrogen to the second material, wherein
- the generation step and the second reduction step are repeated a plurality of times after the first reduction step.
