RESUMO
Constructing S-scheme heterojunction between two semiconductor materials is an effective route to increase the photocatalytic degradation efficiency. Here, a novel S-scheme WS2/BiYWO6 heterojunction photocatalyst was prepared by wet chemical route. At the same time, the photocatalytic degradation performance of the fabricated materials was analyzed by the degradation of Rhodamine B under visible light. Of all prepared WS2/BiYWO6 composites, the 20 wt.% WS2 loaded WS2/BiYWO6 composite exhibited an enhanced photocatalytic degradation ability than other prepared photocatalysts. Here, O2·- and ·OH radicals are performing a pivotal role in the Rhodamine B degradation and the optimized composite shows greater photocurrent intensity than pure BiYWO6 and WS2, respectively. Also, the synthesized photocatalyst maintains its stability with negligible changes even after three cycles. Thereby, the constructed S-scheme WS2/BiYWO6 heterojunction is a potential material for the wastewater remediation.
