A novel S-scheme Ws 2 /BiYWO 6 electrostatic heterostructure for enhanced photocatalytic degradation performance towards the degradation of Rhodamine B

Constructing S-scheme heterojunction between two semiconductor materials is an effective route to increase the photocatalytic degradation efficiency. Here, a novel S-scheme WS /BiYWO 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 WS /BiYWO composites, the 20 wt.% WS loaded WS /BiYWO composite exhibited an enhanced photocatalytic degradation ability than other prepared photocatalysts. Here, O and OH radicals are performing a pivotal role in the Rhodamine B degradation and the optimized composite shows greater photocurrent intensity than pure BiYWO and WS , respectively. Also, the synthesized photocatalyst maintains its stability with negligible changes even after three cycles. Thereby, the constructed S-scheme WS /BiYWO heterojunction is a potential material for the wastewater remediation.
