Highly efficient and stable Ag/Ag3PO4 plasmonic photocatalyst in visible light

One-step Synthesis of Ag3PO4/Ag Photocatalyst with Visible-light Photocatalytic Activity

“…Second, The LSPR produced by the collective oscillations of surface electrons on Ag nanoparticles could enhance the local inner electromagnetic field. The electrons generated by the Ag 3 PO 4 could be separated efficiency with the help of the local electromagnetic field 34 . Finally, PO 4 3-ions own large negative charge and will attract positive holes while repelling electrons.…”

“…Inspired by this study, Ag/Ag 3 PO 4 was successfully synthesized as highly efficient and stable plasmonic photocatalyst [34][35][36] . However, most of the reported synthesis methods require surfactant, such as using pyridine, or in relatively complicated process.…”

Photocatalytic Degradation of Selective Herbicides Using Ag/AgCl/Ag3PO4 Plasmonic Nanocatalyst under Visible Irradiation

“…Among AOPs, heterogeneous photocatalysis has attracted extensive attention for the last a few decades and been proven to be a potential alternative to such currently usual methods as O 3 /UV, H 2 O 2 /UV, O 3 /H 2 O 2 /UV and photo-Fenton for high-performance, energy efficient technology (can use sunlight), possibilities for recycle, eco-friendly property and complete mineralization [5][6][7]. Photocatalysis is based on the irradiation of semiconductor photocatalysts to generate electrons and holes, which can recombine on the surface or be trapped in surface states to form reactive oxygen species (e.g.…”

“…Bi et al [12,13] prepared the heterogenous photocatalysts of AgCl/Ag 3 PO 4 by ion-exchange method to enhance the photocatalytic activity and increase the stability, which were proved through the photocatalytic degradation of dyes. The research by Huang et al [6,14] indicated that the Ag 0 species on the surface of a series of silver salts can enhance the electron-hole separation and improve the photocatalytic activity due to the localized surface plasmon resonance, such as Ag/AgCl, Ag/AgBr, Ag/AgI, Ag/Ag 3 PO 4 et al…”

Visible-light-driven Ag/Ag3PO4-based plasmonic photocatalysts: Enhanced photocatalytic performance by hybridization with graphene oxide

“…More recently, it has been reported that silver orthophosphate (Ag 3 PO 4 ) could be used as highly active visible-light photocatalyst for the photodegradation of organic pollutants [15]. To further enhance photocatalytic activity of this novel material, great efforts have been addressed in terms of morphology-control [16], size-control [17], and hybridization [18,19]. Nevertheless, besides these efforts, it is highly desirable to develop unique yet highly efficient Ag 3 PO 4 -based photocatalysts with enhanced photocatalytic activity to provide more varied and new opportunities for pollutant elimination, and to match the requirements of the future environmental issues.…”
