共价有机骨架材料吸附CO2的研究进展OA

The capture of atmospheric carbon di-oxide by adsorbents is an important strategy to deal with the greenhouse effect.Compared with traditional CO2 adsorption materials like activ-ated carbon,silica gel,and zeolite molecular sieves,covalent organic frameworks(COFs)have excellent thermal and chemical stabilities and can be produced in many different forms.Using their different possible construction units,ordered structures for specific applications can be produced,giving them broad prospects in fields such as gas storage.This review analyzes the dif-ferent types of COFs that have been synthesized and their different methods of CO2 capture.It then discusses different ways to increase CO2 adsorption by changing the internal structure of COFs and modifying their sur-faces.The limitations of COF-derived carbon materials in CO2 capture are reviewed and,finally,the key role of machine learn-ing and computational simulation in improving CO2 adsorption is mentioned,and the current status and future possible uses of COFs are summarized.
