Abstract
2D/2D/2D materials are widely used in photocatalysis owing to the advantages of high specific surface area, large contact interface, numerous charge transfer channels and ultrashort charge transfer distance. In this work, 2D/2D/2D Bi 2WO 6/Ti 3C 2/SnNb 2O 6 catalysts were successfully constructed via an anaerobic hydrothermal method. Due to ultrathin 2D Ti 3C 2 MXene served as an electron mediator and combined with 2D SnNb 2O 6 and 2D Bi 2WO 6 by Ti−O−Sn interface bond or Ti–O–Bi interface bond to form Z-scheme heterojunction, which could afford charge transfer channels and increase reactive sites. As a result, the Bi 2WO 6/Ti 3C 2/SnNb 2O 6 composites significantly improved the photodegradation efficiency of tetracycline hydrochloride due to the high redox ability, and its degradation rate in 90 min was 10.22 times that of SnNb 2O 6 . This work provides an effective method to construct 2D/2D/2D Z-scheme heterojunction by tight chemical bond.
