Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.
