By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Photocatalytics. According to news originating from Zhenjiang, People's Republic of China, by NewsRx correspondents, research stated, "AgI/Ag3PO4 hybrids were synthesized via an ion-exchange method. The structures and morphologies of the samples were characterized by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), UV-vis diffuse reflectance spectroscopy (DRS) and photoluminescence (PL)."
Our news journalists obtained a quote from the research from Jiangsu University, "The results showed that AgI nanoparticles were uniformly distributed on the surface of Ag3PO4 and the heterostructure was formed. DRS of the AgI/Ag3PO4 composites exhibited strong absorbance in Ultraviolet (UV) and visible regions. PL analysis indicated a more efficient separation of electron-hole pairs in the AgI/Ag3PO4 nanocomposites. Under visible light (lambda > 400 nm), the photocatalytic activity of the AgI/Ag3PO4 composites for photodegradation of rhodamine B were efficient and much higher than that of the pure Ag3PO4 crystals. The enhancing photocatalytic activity of AgI/Ag3PO4 was attributed to the efficient separation of electron-hole pairs derived from the matching band potentials between AgI and Ag3PO4."
According to the news editors, the research concluded: "A photocatalytic mechanism and the photocatalytic reaction kinetics over AgI/Ag3PO4 hybrid materials were also proposed."
