BIOMIMETIC SYNTHESIS OF FePt NANOPARTICLES ON MULTI-WALLED CARBON NANOTUBES FOR FUNCTIONAL NANOMATERIALS

Abstract

We present a facile green biomimetic synthesis of FePt nanoparticles (NPs) on the sidewalls of multi-walled carbon nanotubes (CNTs). A core-shell globular protein, ferritin (Fr), was bound onto Z-glycine N-succinimidyl ester (Z-Gly-OSu) modified CNTs and served as precursor to create FePt NPs at the core part of Fr. Biomimetic synthesis of FePt NPs was carried out by chemical reducing of Fe2+ and [Formula: see text] ions that transferred into the core part of Fr molecules. The created one-dimensional CNT- FePt nanohybrids were characterized by transmission electron microscopy and X-ray photoelectron spectroscopy. The synthesized CNT- FePt nanohybrids show multi-properties of high water-solubility, ferromagnetism, and electrocatalytic activity.
