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

Semiconductor photocatalysts are promising cost-effective materials for degrading hazardous organic contaminants in water. AgPO is an efficient visible-light photocatalyst for the oxidation of water and dye degradation. The excited AgPO photocatalyst uses a hole to oxidise water or organic contaminants except the electron, which reduces Ag to Ag.
