Trimetallic Au-Ag-Cu Joint Doped Hydroxyapatite: Synergistic Photo-Fenton-Like Catalytic Performance Enhancement.

ABSTRACT: Photo-Fenton oxidation, as a promising wastewater treatment technology, suffers from double barriers: the sluggish Fenton catalytic rate of transition metal ions and inefficient visible light absorption, both of which severely constrain the performance enhancement of catalytic systems. Therefore, accelerating electron transfer processes and broadening optical absorption spectra have become critical scientific challenges for practical implementation. Herein, a composite catalyst system based on Au-Ag-Cu trimetallic species codoped on hydroxyapatite (HAp) was reported via an ion/ligand impregnation method. AuAgCu/HAp catalyst exhibited superior performance in methylene blue degradation, achieving 100% removal efficiency within 30 min, significantly outperforming mono- or bimetallic doped HAp
