Construction of novel BiOCl/MoS2 nanocomposites with Z-scheme structure for enhanced photocatalytic activity

In this study, novel BiOCl/MoS2 nanocomposites with Z-scheme structure were successfully obtained by a facile one-step hydrothermal method, and the products were evaluated by XRD, SEM, XPS, DRS. Results showed that the MoS2 nanosheets adhered well to surface of the BiOCl, and the BiOCl/MoS2 possessed an excellent Rhodamine B degrading rate of 98.6% within 21 min under visible light irradiation. Radical trapping experiments indicated that center dot OH and h+ were main reactive species responsible for the degradations. The fantastic Z-scheme structure of the BiOCl/MoS2 heterogeneous not only retained the photogenerated holes with higher redox ability but also decreases their recombination rate.
