The enhancement mechanism of ultra-active Ag3PO4 modified by tungsten and the effective degradation towards phenolic pollutants

Sunlight driven isotropic β-Bi2O3 with high charge-carrier mobility for the efficient degradation of bisphenol A and phenol

“…1 Bisphenol A and phenol are two typical representatives of phenolic compounds. 2 Bisphenol A is widely used to produce polycarbonate plastics and epoxy resins 3 while phenol is used in the production of resins, preservatives, bactericides, and drugs. 4 Their accumulation in water seriously interferes with the normal circulation of water and their toxicity induces biological carcinogenesis.…”

Preparation and Characterization of Tubelike g-C3N4/Ag3PO4 Heterojunction with Enhanced Visible-Light Photocatalytic Activity

“…However, Ag 3 PO 4 is prone to photoelectron corrosion and becomes unstable during photocatalytic reaction, which severely limits the application of Ag 3 PO 4 in the field of photocatalysis. Therefore, the photocatalytic performance of Ag 3 PO 4 was improved by adjusting the morphology [16,17], combining it with carbon materials [18,19], and constructing a heterojunction [20,21]. Among them, the Ag 3 PO 4 -based heterojunction can effectively separate electrons and holes according to energy band theory, which is regarded as the most effective method to improve the photocatalytic performance of Ag 3 PO 4 .…”

A novel g-C3N4 nanosheet/Ag3PO4/α-Bi2O3 ternary dual Z-scheme heterojunction with increased light absorption and expanded specific surface area for efficient photocatalytic removal of TC

“…2(d)), two peaks at 368 eV and 374 eV corresponded to the characteristic Ag d 5/2 and Ag d 3/2 peaks derived from Ag + ions of AP, respectively. 20 Moreover, the Ag 3d (Fig. S1(b) †) and survey (Fig.…”

“…The peaks at binding energies of 529.6 eV, 530.6 eV and 531.3 eV were ascribed to the lattice oxygen in the BO, the surface adsorbed water and the P and O atoms of P-O in AP, respectively. 20,36 The signal peak of P 2p was almost invisible because of its low content (Fig. S1 †).…”

“…4 As a typical n-type visible-light photocatalyst, Ag 3 PO 4 (AP) has attracted significant attention because of its high photocatalytic oxidation ability which originated from its strong visible light absorption and the high valence band (VB) edge potential. 20,21 Nevertheless, AP faces the problems of easy recombination of electron-hole (e − -h + ) pairs and photoetching when it exists alone. Some researchers have reported that Z-scheme Ag 3 PO 4 /g-C 3 N 4 composites display excellent photo-stability and enhanced photocatalytic efficiency because of the rapid separation of photo-induced carriers.…”
