[ Instrument R & D of Instrumentation Network ] Recently, Wu Zhongshuai, a researcher of the 2D Materials and Energy Devices Research Group of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Cheng Huiming, Institute of Metal Research, Chinese Academy of Sciences, and Tsinghua-Berkeley Shenzhen College, were invited to publish the title "Graphene "The Chemistry and Promising Applications of Graphene and Porous Graphene Materials" review article.
Graphene is one of the key new materials for China's "Thirteenth Five-Year Plan", and is listed as advanced basic materials, key strategic materials and cutting-edge new materials. Because graphene has an ultra-thin two-dimensional structure and excellent mechanical, optical, and electrical properties, it is predicted that in the near future, it will be possible to achieve greater industrialization progress in the fields of energy storage, thin films and coatings, and composite materials. The research team has been devoted to the controllable preparation of high-quality graphene materials, the design and assembly of graphene macro bodies, and high-efficiency electrochemical energy storage devices (lithium ion batteries, supercapacitors, flexible / miniature energy storage), etc. Applied basic research and achieved a series of original research results.
Based on the previous research foundation, the team systematically reviewed the research progress of the chemistry and application prospects of graphene and porous graphene materials. First, the review introduces the surface interface chemistry, assembly chemistry, and functional chemistry of graphene in detail, focusing on the construction methods of different pore graphene materials (including in-plane pore-forming materials, 2D layered pores, and 3D assembly pore materials) , Revealing the regulation mechanism of different pore structures and the importance of surface chemical modification.
Secondly, this review discusses the structure-activity relationship of different graphene and porous graphene materials in important applications such as supercapacitors, secondary batteries, electrocatalysis, seawater desalination, gas separation, etc., and emphasizes that porous graphene materials have graphene and The double advantage of porous materials. Finally, the review briefly discusses the challenges faced by graphene and porous graphene materials, and proposes feasible solutions and future development directions from the perspectives of bionic chemistry, assembly chemistry, and surface interface chemistry. This review provides some scientific guidance for understanding graphene chemistry, controllable preparation and rational construction of graphene materials and their important applications.
The review was published in "Advanced Functional Materials". The above work was funded by the National Key R & D Program Project, National Natural Science Foundation Project, Postdoctoral Foundation Project, etc.
