Highly photocatalytic activity of novel nano-sized Ag3PO4 for Rhodamine B degradation under visible light irradiation

Room-temperature synthesis of Ag3PO4 nanoparticles with the assistance of trisodium citrate for photocatalytic dye degradation

“…14 A similar UV-vis spectrum was also observed for the Ag 3 PO 4 NPs prepared with OM as the surface additive. 25 In addition, the strong UV-vis absorption of the Ag 3 PO 4 NPs prepared with the other method was considered to come from the presence of both the surface additive and metallic silver. 26 In our experiment, the color of the as-prepared samples changed from yellow to dark yellow and then to brown, which may be due to the generation of some Ag elements on the Ag 3 PO 4 NPs surface, resulting in absorption in the UV region.…”

Effect of Phosphate Salts (Na3PO4, Na2HPO4, and NaH2PO4) on Ag3PO4 Morphology for Photocatalytic Dye Degradation under Visible Light and Toxicity of the Degraded Dye Products

“…For the Ag 3 PO 4 , several research groups − have reported that both ·OH and ·O 2 – species are not the main reactive species in this photocatalytic process, but the reactivity comes from the interaction between the photoinduced holes with the pollutant molecules. The direct hole oxidation can degrade not only dye molecules but also phenolic compounds such as bisphenol A, as presented in Supporting Information Figure S2, and that is in agreement with the results reported by Katsumata et al…”

“…In recent years, silver phosphate (Ag 3 PO 4 ) is a new type of photocatalyst that is highly effective in visible light. − Yi et al reported that Ag 3 PO 4 has a direct band gap of about 2.43 eV that can absorb energy with a wavelength shorter than about 530 nm. The dominant active species in the photocatalytic degradation process using Ag 3 PO 4 as photocatalyst has been reported to produce photoinduced holes .…”

In-situ synthesis of plasmonic Ag/Ag3PO4 tetrahedron with exposed {111} facets for high visible-light photocatalytic activity and stability

“…In past years, many new visible light active photocatalysts, such as doped ZnO [6], BiVO 4 [7], AgX (X¼ Cl, Br) [8,9] and Ag 2 CO 3 [10] have been studied. Recently, Ag 3 PO 4 was reported to be an excellent visible-light driven photocatalyst for its extremely high photooxidative capability for O 2 evolution from water and organic pollutants photodegradation [11][12][13][14]. More specifically, Ag 3 PO 4 photocatalyst can achieve an extremely high quantum yield of about 80% under visible-light irradiation [15], which is significantly higher than the previous reports.…”
