چکیده
In this work, a novel Z-scheme MoS2/CdIn2S4 (MS-CIS) face-to-face heterostructure with excellent photocatalytic activities for multiple organic pollutant degradation was designed and constructed by green mild in-situ hydrothermal method, where CdIn2S4 nano-octahedra coated on the surfaces of ultra-thin MoS2 nanosheets to form interface contact. The performance systematically evaluated Oxytetracycline (OTC) under simulated visible light condition. Compared CdIn2S4, as-obtained MS-CIS-3 sample showed significantly improved toward OTC degradation, rate constant 1.29959 h−1, which 2.31 34.16 times those (0.56303 h−1) (0.03804 h−1). reason improvement in that MS-CIS possessed larger contact area could provide more charge transfer nanochannels, effectively shorten photogenerated electron transport path increase electron-hole separation efficiency. addition, possible reaction routes mechanism were also discussed detail. Furthermore, photostability repeatability outstanding both tetracycline hydrochloride (TCH) 2-Mercaptobenzothiazole (MBT). This work may promising strategy synthesize other photocatalysts highly efficient activity solve environmental pollution.
