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.
