Highlights: • A novel CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure is fabricated by a facile method. • The growth process of CC@MoS{sub 2} is investigated. • The heterostructure displays an excellent photocatalytic property. • Cyclic Voltammetry is utilized to investigate the photocatalytic mechanism. - Abstract: A novel CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure, composed of Ag{sub 3}PO{sub 4} nanoparticles decorated MoS{sub 2} nanosheets on carbon fiber cloth (CC), is fabricated by a simple hydrothermal method and a successive ionic layer absorption reaction. The CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure displays an excellent photocatalytic activity of ∼96% degradation rate for RhB solution under simulated daylight, which is more than 10 times as much as that of pure Ag{sub 3}PO{sub 4} or MoS{sub 2}. The CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure with optimized photoactivity is investigated by optical and electrochemical measurements. The CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure can not only broaden the photoresponse range of MoS{sub 2}, but also alleviate the photodegradation of Ag{sub 3}PO{sub 4}, and the easily separated CC provides a proper conductive substrate and rapid charge transfer channels. The probable photocatalytic mechanism of CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure is discussed in detail. Therefore, the CC@MoS{sub 2}-Ag{sub 3}PO{sub 4} heterostructure with high efficient photocatalytic performance and easy separation is a promising photocatalytic material.
