摘要：
Ag3PO4 nanoparticles have been successfully synthesized by precipitation of AgNO3 and H3PO4 in the presence of oleylamine. The products were characterized by XRD, UV-vis and FE-SEM. It showed that the particle sizes of products ranged from 5 to 10 nm depending on the synthesis conditions. UV-vis result revealed a strong light absorbance in the visible light region at 470-475 nm. Photocatalytic activities of TiO2 and Ag3PO4 nanoparticles were tested in photocatalytic degradation of Rhodamine B (RhB) under visible light irradiation. In comparison to nano-TiO2, nano-sized Ag3PO4 samples exhibited much higher photocatalytic activity in the RhB degradation. After 3 h of reaction, the conversion reached the value of 96%.
