Amine-Functionalized Covalent Organic Framework for Efficient SO2 Capture with High Reversibility

Abstract Removing sulfur dioxide (SO2) from exhaust flue gases of fossil fuel power plants is an important issue given the toxicity of SO2 and subsequent environmental problems. To address this issue, we successfully developed a new series of imide-linked covalent organic frameworks (COFs) that have...
