<P><B>Abstract</B></P> <P>Zinc oxide (ZnO) nano-particles were chemically deposited onto montmorillonite (MONT) clay particles. The composite ZnO@MONT was then characterized and used as a catalyst for photo-degradation of aqueous tetracycline. Unlike earlier studies, solar simulated light can be effectively used in this work. The composite shows high efficiency as adsorbent and as a photo-degradation catalyst. Both adsorbed and dissolved tetracycline molecules undergo mineralization under the photo-catalytic conditions, and up to 94% of the contaminant gross amount is completely mineralized. Other forms of ZnO particles, commercial ZnO and synthetic ZnO particles were examined in separate experiments. The ZnO@MONT is superior to both pristine counterparts. The ability of tetracycline to sensitize the supported ZnO particles, to solar simulated light, before being photo-degraded itself, is discussed here for the first time. In addition to enhanced catalytic activity of the ZnO@MONT, the composite can be efficiently recovered and reused with no significant loss of efficiency.</P> <P><B>Highlights</B></P> <P> <UL> <LI> ZnO particles supported onto montmorillonite are useful catalyst for tetracycline degradation by simulated solar light. </LI> <LI> The ZnO@MONT is more effective catalyst than pristine ZnO, due to high adsorption by support. </LI> <LI> Contaminant facilitates own light-driven degradation by sensitizing the wide bad gap ZnO catalyst. </LI> <LI> ZnO@MONT catalyst can be recovered and reused with no significant loss in its efficiency. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>Tetracycline may self-sensitize its own degradation with simulated solar light Using ZnO supported onto montmorillonite.</P> <P>[DISPLAY OMISSION]</P>
