Bi₂S₃/MoS₂/g-C₃N₄ nanocomposite was synthesized using a solid-state method for the first time. Thiourea and bulk Bi₂MoO₆ were used as the precursors and were reacted under a nitrogen atmosphere. Bi₂S₃/MoS₂/g-C₃N₄ was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microcopy, X-ray photoelectron spectra and ultraviolet–visible diffuse reflectance spectroscopy. The structure of Bi₂S₃/MoS₂/g-C₃N₄ is a three-dimensional network structure formed by uniform loading of g-C₃N₄ and MoS₂ around the rod-like Bi₂S₃ framework. The photodegradation performance was evaluated by the degradation of rhodamine B during irradiation by a 350 W Xe lamp. The degradation rate of Bi₂S₃/MoS₂/g-C₃N₄ towards rhodamine B reached 95.1% after irradiation for 150min. This study will provide new insights into the design of efficient and stable heterostructures for photocatalytic applications.
