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
