Advanced Science, EarlyView.Introducing energetic Cu‐based metal salts into the covalent organic frameworks (COFs) structure, Cu is in single‐atom form anchored to the framework, with energetic anions confined in the COFs structure. The synergistic interaction between single Cu atoms and the anions accelerates the reaction kinetics of ammonium perchlorate (AP) decomposition ...

Iron‐Based Catalysts for the Removal of Microplastics
Advanced Energy and Sustainability Research, EarlyView.Microplastics (MPs) are some of the newer environmental dangers and are still in need of optimal treatment. Iron‐based compounds can be used as catalysts for the removal of MPs due to the iron abundance, sustainability, and catalytic versatility. This review presents the current status of iron‐based materials for the photocatalytic, Fenton process, and
