Removal of silver nanoparticles by mussel-inspired Fe₃O₄@ polydopamine core-shell microspheres and its use as efficient catalyst for methylene blue reduction.

ABSTRACT: The removal of silver nanoparticles (AgNPs) from water is highly needed because of their increasing use and potential risk to the environment due to their toxic effects. Catalysis over AgNPs has received significant attention because of their highly catalytic performance. However, their use in practical applications is limited due to high cost and limited resources. Here, we present for the first time that the mussel-inspired Fe₃O₄@polydopamine (Fe₃O₄@PDA) nanocomposite can be used for efficient removal and recovery of AgNPs. Adsorption of AgNPs over Fe₃O₄@PDA was confirmed by TEM, FT-IR, XRD, TGA and magnetic property. The adsorption efficiency of AgNPs by Fe₃O₄@PDA was investigated as a function of pH
