文摘

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 % .
