SYNTHESIS AND MORPHOLOGY OF CO/AUBIMETAL NANOPARTICLES WITH CORE-SHELL STRUCTURE
Abstract
Bimetal systems of Co/Au nanoparticles with core-shell structure were synthesized by the reduction – electrochemical replacement reaction in aqueous solutions. The core-shell structure is proved by spectroscopy in the visible area and by SAXS. Structure and properties of Co/Au nanoparticles can be successfully described by the «core-shell»model of spherical shape. Mass functions of particle size distribution were computed from the small-angle X-ray scattering curves in the approximation of homogeneous spherical particles and of the «core-shell» model. Evaluation of size and morphology of Co/Au particles in the assumption of «core-shell» model based on analysis of profile of particle size distribution function was performed.
