Ag/Ag₃PO₄/g-C₃N₄ (g denotes graphitic) was synthesized via an anion-exchange precipitation method, and its photocatalytic activity under visible light and regeneration with H₂O₂ and NaNH₄HPO₄ were investigated. The structural characteristics were analyzed using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), ultraviolet-visible (UV-Vis) absorption spectroscopy, and X-ray photoelectron spectroscopy (XPS). The XRD results showed that the structure of the regenerated catalyst was unchanged. The FESEM and UV-Vis absorption spectroscopy results showed that the Ag/Ag₃PO₄/g-C₃N₄ catalyst was composed of Ag₃PO₄ and g-C₃N₄. XPS showed that a small amount of Ag particles were present on the catalyst surface. The photocatalytic activity was evaluated using phenol degradation under visible light (λ>420 nm) and the photocatalytic mechanism was discussed based on the active species during the photocatalytic process and the band structure. Experimental studies showed that the photocatalytic activity of the as-prepared Ag/Ag₃PO₄/g-C₃N₄ was higher than those of pure Ag₃PO₄ and g-C₃N₄. The high photocatalytic performance of the Ag/Ag₃PO₄/g-C₃N₄ composite can be attributed to the synergistic effect of Ag₃PO₄, g-C₃N₄, and a small amount of Ag⁰. Regeneration using H₂O₂ and NaNH₄HPO₄? 4H₂O fully restored the photoactivity of the catalyst, showing that this green regeneration method could make Ag/Ag₃PO₄/g-C₃N₄ an environmentally friendly catalyst for practical applications.
