Supercritical CO₂‐Induced Amorphization in 2D Materials: Mechanism and Applications

Abstract Supercritical carbon dioxide (SC CO 2 )‐assisted chemical and material processing has shown great success in the fabrication of 2D amorphous materials, while the amorphization mechanism in SC CO 2 is quite complicated to be understand. In this review, we introduce different kinds of 2D amorphous materials prepared with SC CO 2 and discuss the possible amorphization mechanism and how they affect the structures and properties of 2D materials. Their applications are further presented and discussed. In addition, the prospective of future development of SC CO 2 ‐assisted fabrication of 2D amorphous materials is also involved. The investigation of SC CO 2 induced amorphization not only provides theoretic understanding of amorphization process, but also directs to the preparation and application of 2D amorphous materials with specific structure and property, suggesting the promising future of SC CO 2 ‐assisted process in material design and engineering.
