Applications
1) Carbon dioxide capture: It has a high adsorption capacity for carbon dioxide under ambient conditions and can be used for post - combustion carbon dioxide capture.
2) Biogas purification: It can separate carbon dioxide from biogas, as confirmed by simulated breakthrough experiments on carbon dioxide/methane mixtures.
3) Magnetic materials: With a magnetic hysteresis loop and canted antiferromagnetism, it can be used for magnetic material research.
4) Gas adsorption: It has a microporous structure and can be used for gas adsorption research (The gas adsorption application is not deeply explored in the article, which mainly focuses on magnetism).
