Title:
IRON OXIDE COMPOSITE INCLUDING DOUBLE LAYER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2023/054840
Kind Code:
A1
Abstract:
The present invention relates to an iron oxide composite including a double layer and a method for producing same. The iron oxide composite including the double layer according to the present invention has a greater number of functional groups attached to the outermost portions due to the double layer structure, and thus exhibits an improved ability to absorb carbon dioxide, can be reused in practice because carbon dioxide can be desorbed by raising temperature, and can be easily collected due to exhibiting magnetism.
