Facile synthesis and photocatalytic activity of Ag3PO4 decorated MoS2 nanoflakes on carbon fiber cloth

A novel CC@MoS 2 -Ag 3 PO 4 heterostructure, composed of Ag 3 PO 4 nanoparticles decorated MoS 2 nanosheets on carbon fiber cloth (CC), is fabricated by a simple hydrothermal method and a successive ionic layer absorption reaction. The CC@MoS 2 -Ag 3 PO 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 3 PO 4 or MoS 2 . The CC@MoS 2 -Ag 3 PO 4 heterostructure with optimized photoactivity is investigated by optical and electrochemical measurements. The CC@MoS 2 -Ag 3 PO 4 heterostructure can not only broaden the photoresponse range of MoS 2 , but also alleviate the photodegradation of Ag 3 PO 4 , and the easily separated CC provides a proper conductive substrate and rapid charge transfer channels. The probable photocatalytic mechanism of CC@MoS 2 -Ag 3 PO 4 heterostructure is discussed in detail. Therefore, the CC@MoS 2 -Ag 3 PO 4 heterostructure with high efficient photocatalytic performance and easy separation is a promising photocatalytic material.
