摘要:
A novel Z-scheme Ag-decorated g-C3N4/B2WO6 composite is successfully synthesized by introducing Ag NPs on the interface of g-C3N4/Bi2WO6 composite. The Ag-decorated g-C3N4/Bi2WO6 sample exhibits much higher photocatalytic activity than g-C3N4/Bi2WO6 composite on the degradation of Rhodamine B under visible light. The significantly enhanced catalytic efficiency could be attributed to the Z-cheme transfer mechanism of photogenerated electron-hole pairs, which was confirmed by investigating the morphology, structure, optical properties and photocatalytic activities.
