Abstract

The silver phosphate (Ag3PO4) sample was synthesized using Na3PO4, AgNO3 and PEG-10000 as raw materials by the hydrothermal method. Its different morphologies were obtained by changing temperature and surfactant. And its structures and morphology were characterized by X-ray diffraction and field emission scanning electron microscopy. The result of the study indicated that after the heat treatment at 150°C, the as-obtained Ag3PO4 polyhedral microcrystal’s diameter was about 4 μm. Meanwhile, it showed that using Ag3PO4 polyhedral microcrystals as photocatalysts, the photocatalytic degradation rate of methylene blue in aqueous solution was close to 98.5% after 25 min of sunlight.
