One-pot green synthesis of Ag/Ni/Fe₃O₄-activated carbon beads for recyclable photo-Fenton antibiotic removal and antibacterial action: mechanistic study and optimization.

ABSTRACT: A one-pot green synthesis approach was developed to fabricate Ag/Ni/Fe₃O₄-activated carbon beads (Ag/Ni/MACB) using Brucea javanica as a natural carbon precursor. Unlike conventional powdered catalysts, these millimeter-sized porous beads enable easy recovery and reusability, addressing a key limitation in heterogeneous Fenton systems. The Fe₃O₄ component facilitated Fenton-like reactions, while Ni and Ag nanoparticles synergistically enhanced electron transfer and visible-light absorption, significantly boosting photo-Fenton efficiency. The catalyst achieved 96.78% enrofloxacin (ENR) degradation under optimized conditions, with radical scavenger experiments confirming that ˙OH and ˙O₂ ^- were the dominant reactive spe
