A MOF-on-MOF strategy to construct double Z-scheme heterojunction for high-performance photocatalytic degradation

Hassan Sepehrmansourie et al.

Summary: In this study, a double Z-scheme heterojunction material UiO-66/NH2-MIL-125/g-C3N4 was developed for the degradation of OFL antibiotics under visible light irradiation. The material exhibited high photocatalytic activity and a significantly higher degradation rate constant compared to pristine UiO-66/MIL-125. Radical trapping and EPR experiments confirmed the essential role of (OH)-O-center dot and O-center dot(2)- in OFL photodegradation. This research not only provides a novel approach to construct MOF on other MOFs but also offers a new method for removing emerging pollutants from wastewater.
