Solar‐Responsive Zr‐MOF/Ag4P2O7 Heterostructures for Sustainable Photocatalytic Degradation of Emerging Water Contaminants

Advanced Sustainable Systems, EarlyView.
A microwave‐assisted approach yields Zr‐MOF/Ag4P2O7 heterostructures with superior solar responsiveness and efficient charge‐carrier separation. The hybrid photocatalyst rapidly degrades dyes and fluoroquinolone antibiotics into less toxic species under visible‐light.
