Graphdiyne has broad application prospects and my country’s R&D enthusiasm is high
Graphyne refers to an all-carbon molecule composed of benzene rings conjugated by 1,3-diyne bonds to form a two-dimensional planar network structure. It is a new all-carbon nanostructure material and is known as the most stable synthetic diyne. Allotropes of carbon. Graphdiyne has the characteristics of good chemical stability, wide interplanar spacing, and large conjugated system, and is expected to show broad application prospects in the fields of optoelectronics, new energy, energy storage, electronics, and information technology.
The main production processes of graphdiyne include dry chemical synthesis and wet chemical synthesis. Dry chemical synthesis refers to using hexaethynylbenzene as raw material and utilizing the coupling reaction of intermolecular terminal alkyne groups on a metal substrate to finally prepare graphyne. This method has many side reactions and needs further improvement. Wet chemical synthesis refers to reacting dissolved hexaynylbenzene with copper foil in an environment full of nitrogen, and finally producing graphyne powder through cleaning, peeling and other processes.
According to the “2023-2028 China Graphdiyne Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, graphite Alkynes have broad application prospects in the fields of optoelectronics, new energy, energy storage, electronics and electrical, information technology, catalysts and other fields. In the field of energy storage, graphdiyne can be used to produce perovskite solar cells, which can effectively improve its photoelectric conversion efficiency; in the field of electronics and electrical appliances, graphdiyne can be used to produce fluorescent sensors, nanosensors, etc.; in the field of catalysts, nitrogen-doped graphyne It has excellent oxygen reduction catalytic activity and resistance to methanol interference, and is expected to replace precious metal platinum catalysts in the future.
my country is the first country to research graphdiyne. In 2010, the team of Academician Li Yuliang of the Institute of Chemistry, Chinese Academy of Sciences took the lead in developing a method for preparing graphdiyne, setting a precedent for the artificial synthesis of diyne carbon allotropes. In 2022, Academician Li Yuliang’s team, Professor Yang Wenlong of Shandong University, and Lu Qiang of China University of Petroleum first discovered a new type of crystalline two-dimensional phosphine graphyne. This material is expected to be widely used in the field of electrode materials.
At present, my country’s graphdiyne industry is still in the laboratory research and development stage and has not yet achieved large-scale application. my country’s graphdiyne companies and related scientific research institutions include Beijing Beike New Material Technology Co., Ltd., Zhengzhou Lianchi Biotechnology Co., Ltd., Beijing Huawei Ruike Chemical Co., Ltd., Fujian Minjiang University, China University of Petroleum, and Shandong University Material Creation and Energy Conversion Scientific Research Center, Institute of Chemistry, Chinese Academy of Sciences, etc.
Industry analysts said that graphyne is a new nanostructured material developed after carbon nanotubes, graphene and fullerene. , which has a variety of excellent properties and shows broad application prospects in energy storage, electronics, catalysts and other fields. At present, graphdiyne research in my country is still in its infancy, and the number of research companies and institutions is growing. In the future, driven by positive factors such as in-depth research, the application scope of graphdiyne will be further expanded.
