Catalytic Growth of a Graphite-Like Shell on Transition Metal Nanoparticles with the Formation of Core–Shell Structures

Abstract

Methods for the production of metal–carbon nanoparticles of the core–shell type based on the formation of transition metal nanoparticles and a graphite-like shell on their surface containing to 50 graphene layers are considered. Various types of high-energy impacts or thermal transformations under exposure in a temperature range of 600–850°С were used for the synthesis of metal–carbon nanoparticles from initial metal- and carbon-containing components. Due to their unique properties, nanoparticles of this kind can be of interest as highly efficient catalysts, targeted drug carriers, contrasts in MRI diagnostics, and an element base of electronic and magnetic devices.
