One-step Synthesis of ZnS@MoS2 core-shell nanostructure for high efficiency photocatalytic degradation of tetracycline

Four kinds of ZnS@MoS2 nanocomposite photocatalysts were successfully prepared via a facile hydrothermal method. The photocatalytic performance of the prepared samples can be significantly affected by means of the content and preparation process of MoS2. The ZnS@MoS2 (3:1) prepared by one step hydrothermal method exhibited the best photocatalytic activity for degradation of tetracycline. Under ultraviolet irradiation, tetracycline is completely degraded after 60 min reaction. After repeated 5 cycles, the degradation rate of tetracycline decreased slightly (1.5%), indicating that ZnS@MoS2 (3:1) performs a high efficiency and stable photocatalytic performance for degradation of tetracycline, which owns a broad prospect for industrial application.
