- •
Ag3PO4 was initially prepared via ion-exchange reaction and then annealed in air.
- •
Thermal annealing also resulted in the formation of metallic Ag and Ag vacancies.
- •
The annealed samples exhibited superior activity to the pristine sample.
- •
Both Ag vacancies and metallic Ag contributed to the high activity.
