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

Abstract

The cubic silver phosphate (Ag3PO4) nanoparticles (NPs) are prepared with the assistance of trisodium citrate. By control the reaction time, different size of Ag3PO4 was obtained. The possible growth mechanism...

Efficient Solar Light Photocatalyst Made of Ag3PO4 Coated TiO2-SiO2 Microspheres

“…The SEM micrograph of the composite catalyst TS82/AgP16 in Figure 2 c shows that the Ag 3 PO 4 nanoparticles are uniformly distributed on the surface of TS82 microspheres and titania silica microspheres are decorated with Ag 3 PO 4 nanoparticles with an average size of 40 nm (inset of Figure 2 d). It is also noteworthy to observe that in case of pristine Ag 3 PO 4 , aggregated particles of 200 to 300 nm were formed due to rapid nucleation in the reaction solution leading to crystal growth [ 43 ]. However, this feature is absent in the composite material indicating that the TS82 microspheres act as nucleation controlling medium leading to nearly uniform distribution of the small sized (~50 nm) Ag 3 PO 4 nanoparticles.…”

Preparation of Ag3PO4tetrapods anchored to nitrogen-doped carbon quantum dots for enhanced photocatalytic performance

“…6 In many narrow-bandgap semiconductors, silver phosphate (Ag 3 PO 4 ) has a highly dispersed conduction band and good electrostatic induction, which can accelerate the separation of photo-generated carriers, thus exhibiting unparalleled high quantum efficiency. [7][8][9] In recent years, researchers have demonstrated that Ag 3 PO 4 exposed with different active facets has significantly different photocatalytic properties. 10 Among them, Ag 3 PO 4 tetrapods exposed to high-reactive {110} facets have better photocatalytic performance due to its double coordination of multiple suspended bonds, which can provide more active sites.…”

Three novel coordination polymers as bifunctional materials for the photocatalytic degradation of dyes and the oxygen evolution reaction in alkaline solutions

“…At present, water pollution treatment methods include biological treatment, 6 physical adsorption, 7,8 chemical oxidation, 9 and photocatalytic degradation. 10,11 Among them, photocatalysis stands out among many methods due to its advantages of low cost, high degradation rate, environmental friendliness, and no formation of secondary pollutants. 12…”
