Abstract

Since the 21st century, a variety of photocatalytic materials have been developed, in which the properties are not the same, but the photocatalytic degradation activity of Ag3PO4 is much higher than other known visible light catalysts, and Ag3PO4 exhibits excellent performance under visible light. Photocatalytic performance has received attention. In order to prepare a more stable and efficient Ag3PO4 photocatalytic material, the photocatalytic performance of Ag3PO4 was improved by nano-metal Ag modification of Ag3PO4. Nano-modified silver phosphate was prepared by coprecipitation method and hydrothermal method using silver nitrate and potassium dihydrogen phosphate as raw materials, and analyzed by x-ray diffraction (XRD), scanning electron microscope (SEM), Photoluminescence (PL), ultraviolet diffuse reflection and photodegradation etc. The performance improvement effect of the prepared nano-metal modified silver phosphate was examined. In this experiment, Rhodamine was used as the degraded solution. Through the photodegradation experiment, that is, under the illumination of LED lamps, it can be observed that the performance of nano-metal Ag-modified silver phosphate is improved compared with pure Ag3PO4, and the prepared nano-metal Ag is modified. The degradation rate of rhodamine at Ag3PO4 can reach 99% at 10 minutes.
