In suit constructing S-scheme FeOOH/MgInS heterojunction with boosted interfacial charge separation and redox activity for efficiently eliminating antibiotic pollutant.

Photocatalytic elimination of antibiotic pollutant is an appealing avenue in response to the water contamination, but it still suffers from sluggish charge detachment, limited redox capacity as well as poor visible light utilization. Herein, a particular S-scheme FeOOH/MgInS heterojunction with wide visible light absorption was triumphantly constructed by in-situ growth of MgInS nanoparticles onto the surface of FeOOH nanorods, and employed as a high-efficiency visible light driven photocatalyst for removing tetracycline (TC). Conspicuously, the as-obtained FeOOH(15 wt%)/MgInS elucidated the optimal TC removal rate of 0.
