Thin silica shell on Ag₃PO₄ nanoparticles augments stability and photocatalytic reusability.

ABSTRACT: Semiconductor photocatalysts are promising cost-effective materials for degrading hazardous organic contaminants in water. Ag₃PO₄ is an efficient visible-light photocatalyst for the oxidation of water and dye degradation. The excited Ag₃PO₄ photocatalyst uses a hole to oxidise water or organic contaminants except the electron, which reduces Ag⁺ to Ag⁰. In the present study, the inherited disadvantage was overcome by a thin silica shell overcoating on Ag₃PO₄ nanoparticles. The silica-coated Ag₃PO₄ nanoparticles retain the photocatalytic activity even after five cycles of photodegradation, while the bare Ag₃PO₄ nanoparticles show a photocatalytic activity declin
