As an emerging class of two-dimensional materials, two-dimensional transition metal telluride materials have shown important application potential in fields such as quantum communications, catalysis, energy storage, and optics due to their unique physical and chemical properties such as superconductivity, magnetism, and catalytic activity. , has received widespread attention from the international academic community. However, this material is currently unable to achieve high-quality macro-scale preparation, which hinders its practical application and triggers scientists to continue to invest in research.
The latest news from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, says that the team of researcher Wu Zhongshuai and collaborators from the institute have innovatively developed a new method that can prepare niobium telluride nanosheets at a scale of two orders of magnitude, and have proven that It has universal applicability, thus providing the possibility for large-scale preparation of two-dimensional transition metal telluride materials.
The solutions and powders prepared from the two-dimensional transition metal telluride nanosheets prepared by this method have good processing properties and can be used as various functional slurries to realize thin films, screen printing devices, 3D printing devices, and photolithography devices. High-efficiency and customized processing are expected to play an important role in high-performance quantum devices, flexible electronics, micro-supercapacitors, batteries, catalysis, electromagnetic shielding, composite materials, etc.
This paper, which has made important breakthroughs in the macro-preparation of two-dimensional transition metal telluride materials, was jointly conducted by Wu Zhongshuai's team and academician Cheng Huiming of the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences and the Institute of Metal Research, Chinese Academy of Sciences, and Peking University Electronics It was completed in collaboration with Associate Professor Kang Ning of the college and was published online in the internationally renowned academic journal "Nature" late at night on April 3rd, Beijing time. Reviewers commented that this method is simple, fast, efficient, and has universal significance for the macropreparation of two-dimensional materials.
The research team provided two animations to the media to demonstrate the results of this research.
