摘　　要：二维非晶材料不仅具有二维材料的高比表面积和高表面原子活性,还具有非晶材料的多缺陷和活性位点等优势,是理想的催化材料。近年来,超临界二氧化碳辅助制备工艺在制备二维非晶材料方面取得了一系列成功。介绍了利用超临界二氧化碳辅助制备各种二维非晶材料,讨论了其可能的非晶化机理及其对二维材料结构和性能的影响,并进一步展示了它们在不同领域的应用。对超临界二氧化碳辅助制备二维非晶材料的研究不仅能从理论层面理解二维非晶材料的形成机制,更为制备具有特定结构和性能的二维非晶材料提供指导。相关研究展示了超临界二氧化碳辅助制备工艺在材料设计和工程应用中具有广阔的前景。Two-dimensional(2D)amorphous materials with the high specific surface area,were ideal catalysts,because of their features,such as the high surface atomic activity like two-dimensional materials,and the disordered structure with more defects and active sites.Recently,supercritical carbon dioxide(SC CO2)assisted technology achieved great success in preparing two-dimensional amorphous materials.Varies kinds of 2D amorphous materials fabricated with SC CO2 were introduced,their underlying amorphization mechanism were discussed,and their applications in different fields were further shown.The investigation of SC CO2 assisted fabrication of 2D amorphous materials could not only help us understand the forming mechanism of 2D amorphous structure,but also provid insight into the preparation of special 2D amorphous materials.
