Abstract

Abstract : Polydopamine‐functionalised graphene–Fe3 O4 –Ag composites (PGFA) were fabricated using a facile method. The morphology, structure, and chemical components of PGFA are investigated using various techniques, including X‐ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and X‐ray photoelectron spectroscopy. PGFA exhibits high catalytic activity for the degradation of p ‐nitrophenol. Furthermore, PGFA presents excellent catalytic stability and can be reused successfully for 14 cycles, maintaining high degradation efficiency (>98%). Antibacterial tests show that PGFA offers significant antibacterial potential against E. coli and S. aureus .
