MoSe2/Ag3PO4 Composites: Preparation and Photocatalytic Properties for Degradation of Rhodamine B under Visible Light

The as-prepared MoSe2/Ag3PO4 by in-situ deposition showed favorable photocatalytic, activity and stability. Heterostructure of MoSe2/Ag3PO4 had efficient separation of photogenerated electron-hole pairs that led to the elevated photocatalytic, activity. The transfer of photogenerated electrons from the surface of Ag3PO4 to MoSe2 reduced the possibility of Ag+ to metallic Ag. When the mass ratio of MoSe2 and Ag3PO4 was 1:5 (champion combination ), the obtained MoSe2/Ag3PO4 could reach to 98% for RhB degradation under visible light irradiation within 30 min. In addition, MoSe2/Ag3PO4 still achieved 89% of the degradation under visible light irradiation after four regenerations. Eventually, the photocatalytic degradation of RhB by MoSe2/Ag3PO4 was revealed by liquid chromatography/mass spectrometry (LC/MS).

Automated summary

The MoSe2/Ag3PO4 heterostructure exhibited excellent photocatalytic activity and stability, with efficient separation of electron-hole pairs under visible light irradiation. The optimal mass ratio of MoSe2 and Ag3PO4 was 1:5, achieving a high degradation rate for RhB. MoSe2/Ag3PO4 also showed good durability with 89% degradation after four regenerations under visible light.
