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

Supercritical carbon dioxide (SC CO₂ )-assisted chemical and material processing has shown great success in the fabrication of 2D amorphous materials, while the amorphization mechanism in SC CO₂ is quite complicated to be understand. In this review, we introduce different kinds of 2D amorphous materials prepared with SC CO₂ 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 CO₂ -assisted fabrication of 2D amorphous materials is also involved. The investigation of SC CO₂ 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 CO₂ -assisted process in material design and engineering.
