| Abstract: | Delicate fabrication grounded on 2D epitaxial heterostructure can be identified as an available strategy to sufficiently discover and utilize its preponderances. Herein, bismuth sulfide-bridged Bi2S3/sulfuretted ZnAl-LDHs (Bi2S3/ZnAlSx) heterojunctions were rationally designed and fabricated via simple ion-exchange and hydrothermal treatment methods. The photocatalytic activities of the heterojunction composites were evaluated for the degradation of tetracycline (TC) under visible-light irradiation. Compared to the ZnAl-LDHs and ZnAlSx, the composites showed the best visible-light-driven photocatalytic performance for TC degradation due to the intimate contact between ZnAlSx and Bi2S3. In additional, upon the proper weight ratio of Bi2S3 (20 wt%), the as-synthesized production exhibited the highest photodegradation efficiency for TC (90.89%) under visible-light irradiation. Surprisingly, the apparent reaction rate constant (k) of Bi2S3/ZnAlSx is approximately 3.3-folds higher than ZnAlSx. Moreover, the possible reaction mechanism of the enhanced photocatalytic activity was proposed resulting from inhibited the recombination between photogenerated electrons and holes. Additionally, the 20 wt% Bi2S3/ZnAlSx showed the high removal efficiency (80.18%) for TC pollutants after four continuous cycles. This work underlines the important of heterostructure construction and further testifies that bismuth sulfide-bridged Bi2S3/sulfuretted ZnAl-LDHs (Bi2S3/ZnAlSx) are promising photocatalysts for the decomposition of antibiotics from waste water under visible-light irradiation.
