Facile one-step growth of hierarchical Bi2S3@MoS2 structures for enhanced photocatalytic activity

Abstract

Hierarchical structures composed of MoS2 nanosheets grown on Bi2S3 nanorods, were prepared via hydrothermal reaction. The innovative heterostructures with distinct porosity and close interfacial contact may enable effective visible-light utilization as well as permeable routes for reactant molecules to enter the inner structure. The Bi2S3@MoS2 heterostructure with 50% of MoS2 showed superior adsorption and photodegradation of Rhodamine B, reaching 97.5%. Toxic heavy metal ions and organic pollutants in water may be eliminated utilizing attractive heterostructures with excellent adsorption capacities and photocatalytic activities.
