Title:
METHOD FOR PRODUCING CARBON MATERIAL, CARBON MATERIAL, METHOD FOR DECOMPOSING CARBON DIOXIDE, AND REDUCING AGENT
Document Type and Number:
WIPO Patent Application WO/2022/163836
Kind Code:
A1
Abstract:
The present invention is characterized by having a carbon production step for reacting carbon dioxide and a reducing agent to produce carbon, wherein the reducing agent uses: an oxygen-deficient iron oxide which is represented by Fe3O4-δ (where δ is 1 to 4 (exclusive of 4)), and obtained by reducing magnetite while maintaining a crystal structure; or an oxygen-completely deficient iron (δ=4) obtained by completely reducing magnetite.
