Facile synthesis of tetrahedral Ag3PO4 submicro-crystals with enhanced photocatalytic properties

Abstract

Tetrahedral Ag 3 PO 4 submicro-crystals have been fabricated in highyield by directly reacting commercial Ag foils with H 2 O 2 and NaH 2 PO 4 in aqueous solution at room temperature, which exhibit higher photocatalytic activities than Ag 3 PO 4 cubes, particles, and N-doped TiO 2 for the degradation of organic contaminants under visible light irradiation.

Fabrication of P25/Ag3PO4/graphene oxide heterostructures for enhanced solar photocatalytic degradation of organic pollutants and bacteria

“…Thus the construction of TiO 2 -based composite materials with improved lower band gap is crucial for the increase of the solar energy harvest. Most recently, silver orthophosphate (Ag 3 PO 4 ) has attracted increasing attention owing to its great potential in water splitting and photodegradation of organic pollutants [22][23][24][25][26][27][28][29]. However, Ag 3 PO 4 suffer from poor photostability due to fast photoreducion into metallic Ag.…”

Synthesis of Ag 3 PO 4 -polyvinyl alcohol hybrid microcrystal with enhanced visible light photocatalytic activity

“…Since Yi et al discovered the great photocatalytic activity of silver phosphate [1], modifications of this material have attracted tremendous attention [2][3][4][5][6][7] due to their high performance at the organic pollutant degradation, like that of TiO 2 . The high photocatalytic activity of rhombic dodecahedrons, primarily consisting of higher surface energies of {1 1 0} crystalline planes, was successfully fabricated [2].…”

Ag-based semiconductor photocatalysts in environmental purification

“…Ag 3 PO 4 can be fabricated by different methods, such as precipitation [54][55][56][57], ion exchange [58], hydrotherm [59], electrochemical oxidation [60], and etc. Bi et al [54] prepared Ag 3 PO 4 with size less than 1μm by liquid phase deposition.…”
