Study on Challenges and Solutions for Enhancing Photocatalytic Activities of Ag3PO4Nanoparticles for Degradation of Organic Dyes from Wastewater

Abstract

Improper management of discharged waste material such as toxic organic dyes from industries causes severe health and economic problems because contaminated water with organic dyes is harmful to human being and aquatic ecosystems. The photocatalyst is a preferable wastewater treatment method because it is environmentally benign, cost-wise, and more efficient in degrading dyes. Most metal oxide semiconductors are photocatalytic materials, but nowadays, Ag3PO4 nanoparticles have attracted enormous attention due to their low bandgap and high absorption of visible light. However, Ag3PO4 nanoparticles have low performance due to photocorrosion, high recombination rate, and instability in the solution. Thus, in this review article, the mechanism to enhance the photocatalytic activities of Ag3PO4 nanoparticles was discussed, and the future perspective of the silver phosphate was also stated.
