Facile Synthesis of Ag3PO4 Nanospheres with Enhanced Photocatalytic Properties for the Degradation of Methylene Blue Under Visible Light Irradiation

摘要

A facile and simple sodium hexametaphosphate complex method is proposed for the synthesis of Ag3PO4 nanospheres with highly uniform in size. The morphology, structure, and photoabsorption of the Ag3PO4 nanospheres were characterized. Furthermore, the photocatalytic activities for the decomposition of methylene blue (MB) were also analyzed and the results show that the as-prepared Ag3PO4 nanospheres exhibit excellent visible light driven photocatalytic activities for the photodecomposition of organic contaminants in comparation with microsized Ag3PO4 particles and N-doped TiO2 under visible light irradiation.
