Nanocomposite of attapulgite–Ag3PO4 for Orange II photodegradation

Applied Catalysis B: Environmental, 2014
Abstract Well-spread Ag 3 PO 4 particles (5 nm in size) were synthesized on the surface of attapulgite (ATP) for the sunlight-driven catalytic removal of Orange II from water. The attapulgite–Ag 3 PO 4 composites were characterized by XRD, XRF, XPS and UV–vis diffuse reflectance spectroscopy.

Facet engineered Ag3PO4 for efficient water photooxidation

Energy & Environmental Science, 2013
The photooxidation of water using faceted Ag3PO4 was investigated, guided by theoretical modelling. Firstly, theoretical calculations were performed to predict the optimum morphology for solar energy conversion by probing the surface energies of three primary low index facets of Ag3PO4: {100}, {110} and {111}.

Controlled synthesis and photocatalytic properties of Ag3PO4 microcrystals

Journal of Alloys and Compounds, 2015
Silver phosphates (Ag3PO4) with varied morphology were prepared via an ammonia-mediate method. The as-prepared Ag3PO4 has a cubic-type structure and the morphologies are controlled under different ratio of water and ethylene glycol. The decomposition test of RhB indicated that the uniform morphology of Ag3PO4 exhibit much higher photocatalytic ...

Photocatalytic activity of Ag3PO4 nanoparticle/TiO2 nanobelt heterostructures

Applied Surface Science, 2012
Abstract Heterostructures based on Ag 3 PO 4 nanoparticles and TiO 2 nanobelts were prepared by a coprecipitation method. The crystalline structures were characterized by X-ray diffraction measurements. Electron microscopic studies showed that the Ag 3 PO 4 nanoparticles and TiO 2 nanobelts were in intimate contact which might be exploited to ...

Phase formation in the Ag3PO4-ScPO4 quasi-binary system

Russian Journal of Inorganic Chemistry, 2013
The phase formation in the subsolidus region of the Ag3PO4-ScPO4 quasi-binary system was studied by X-ray powder diffraction and differential thermal analyses throughout the range of concentration ratios of the initial components at an interval of 10 mol % within the temperature range 20–1000°C in air at atmospheric pressure.

Controlled synthesis and characterizations of thermo-stabilized Ag3PO4 crystals

Research on Chemical Intermediates, 2016
Thermal stability of Ag3PO4 crystals was explored, and the calcination treatment was used to diminish the growth defect inside the Ag3PO4 crystals and improve their photoelectric properties. The results of in situ XRD and TG-DSC patterns indicated that Ag3PO4 crystals could maintain the integrality of their crystal structure under 400 °C ...

Structural studies of the high-temperature modifications of sodium and silver orthophosphates, II-Na3PO4 and II-Ag3PO4, and of the low-temperature form I-Ag3PO4

Solid State Ionics, 1980
Abstract The crystal structures of the high-temperature modifications of sodium and silver orthophosphates have been determined using powder neutron diffraction (PND) data. II-Na3PO4 adopts the space group Fm3m with a=7.512(3) A at 400°C. The PO3−4 group is centered around the origin, but it shows high orientational disorder.
