Abstract Heterogeneous photocatalysts based on polyoxovanadates with Keggin structure (POV) supported onto zeolite (NH 4 ZSM‐5) were developed.

The extracted ash from common water reeds locally available in Iraq was used as a cost-effective silica source for single-step synthesis of heterojunction photocatalyst (Ag2O@CRA) combining 9.75 % Ag2O and surface area 99.849 m2/g. Ag2O@CRA to investigate methylene blue (MB) degradation which eliminated at an initial MB concentration 20 mg/L, dose 0.1g/100 mL, pH 7 after 60 min visible light. This displayed excellent stability five cycles with more than 91 removal dye. ⦁OH the main radical involved degradation.
