Synthesis and characterization of Ag/Ag3PO4 nanomaterial modified BiPO4 photocatalyst by sonochemical method and its photocatalytic application

Facile Synthesis and Characterization of Ag3PO4 Microparticles for Degradation of Organic Dyestuffs under White-Light Light-Emitting-Diode Irradiation

“…The Ag 3 PO 4 microparticles (S1–S4) were used to degrade MB and phenol under white-light LED irradiation (5 W, PCX-50C, Beijing perfectlight technology co. LTD, Beijing, China), and their photocatalytic activity was evaluated based on our earlier reports with modifications [ 33 , 34 , 35 , 36 , 37 ]. Prior to irradiation, 50 mL of 5 mg/L MB aqueous solution or 10 mg/L phenol solution containing 50 mg of photocatalyst was stirred in the dark for 30 min.…”

“…The recombination rate of the electron–hole pairs and charge separation efficiency for the Ag 3 PO 4 microparticles (S1–S4) were evaluated based on our earlier reports [ 33 , 34 , 35 , 36 , 37 ]. For determination of recombination rate of electron–hole pairs, photoluminescence spectra were produced using a Varian Cary Eclipse fluorescence spectrometer (Agilent Technologies, Inc., Santa Clara, CA, USA).…”

“…The scavenger test was used to determine the major reactive species involved in the MB degradation. The procedure was similar to that the photocatalytic activity procedure [ 33 , 34 , 35 , 36 , 37 ]. Prior to adding a photocatalyst, hole-, oxygen radical- and hydroxyl radical- scavengers (each 10.0 µM) were added to the MB solution.…”

Recent Advances in the Disinfection of Water Using Nanoscale Antimicrobial Materials

“…Thus, the as‐synthesized composites showed high antibacterial properties under these conditions . An Ag/Ag 3 PO 4 nanomaterial–modified BiPO 4 photocatalyst was fabricated using the sonochemical method, and the enhanced disinfection activity of the resulting photocatalyst can be attributed to the high separation efficiency of e − /h + pairs and the release of Ag + under visible light irradiation . Additionally, taking advantage of GO, Liu et al fabricated the GO–Ag 3 PO 4 composite (Figure J,K) using gauze‐like GO‐enwrapped Ag 3 PO 4 with a rhombic dodecahedral morphology (Figure L), which can adsorb visible light (Figure M).…”

Facile synthesis of Ag 3 PO 4 microcrystals and its enhanced photocatalytic disinfection

“…S. aureus (wild) were used as gram-negative and gram-positive bacterial modes, respectively, in the evaluation of the antibacterial activity of the Ag 3 PO 4 microcrystals (S0 and S1) based on a previously described procedure [20][21][22]. The microbes were cultured at 37°C in a Luria-Bertani (LB) medium.…”
