New Catalyst Design Enhances Water Purification Efficiency and Longevity
Researchers from Huaqiao University and wastewater treatment centers in Xiamen, China, have developed a novel FeS2/MoS2 heterostructure catalyst that significantly improves the efficiency and durability of water purification processes. This catalyst operates through a self-sustaining charge-circulation process, allowing it to regenerate its active sites continuously. This innovation addresses the common issue of catalyst deactivation in advanced oxidation processes, which are crucial for removing persistent micropollutants like pharmaceuticals from water. The system supports both radical and non-radical oxidation pathways, enabling rapid removal of contaminants such as acetaminophen and maintaining high performance across various water types. The catalyst demonstrated over 95.5% retention of its original performance after multiple cycles and sustained more than 91.5% removal efficiency after extended operation.
