2D/1D ZnIn2S4/attapulgite hybrid materials for enhanced photocatalytic performance under visible light
Abstract The 2D/1D structure of ZnIn2S4/attapulgite was constructed by anchoring ZnIn2S4 nanosheets on the surface of attapulgite nanorods for the removal of tetracycline hydrochloride (TC) and rhodamine B (RhB). The 2D ZnIn2S4 was closely combined with the 1D attapulgite, and ZnIn2S4/attapulgite had a higher BET surface area (83.6 m2/g) than pure ZnIn2S4 (13.6 m2/g). The combination of ZnIn2S4 and attapulgite promoted pollutant adsorption by providing more exposed active sites and a larger contact area, which also contributed to enhanced photocatalytic performance. Under visible light irradiation, the as-prepared ZnIn2S4/attapulgite composites exhibited enhanced photocatalytic activity when compared with pure ZnIn2S4. After 9 min (50 min) of irradiation, the optimized ZnIn2S4/attapulgite photocatalyst removed about 99.9% RhB (82.1% TC). In addition, the ZnIn2S4/attapulgite photocatalyst demonstrated excellent photostability and availability. Compared with other photocatalysts, the samples in this work used natural minerals as the carrier, which significantly improved the dispersibility and adsorption performance of the catalyst, and was conducive to the improvement of catalytic performance. This work contributed to the development of photocatalysis for the removal of environmental liquid-phase pollutants.

Highlights 2D/1D ZnIn2S4/attapulgite photocatalyst was synthesized via a facile method. The composite showed excellent performance for degrading of TC and RhB. The outstanding performance may be attributed to the 3D structure of composite.
