Abstract
The chemical compositions, structures, and electrokinetic potentials have been studied for silver-containing Janus-type ZnO/Ag nanoparticles, heterophase Cu/Ag nanoparticles with a uniform distribution of the components over a particle, and silver-decorated TiO2 nanoparticles. The nanoparticles have been obtained by the simultaneous electric explosion of two wires. The influence of nanoparticle surface structure on the isoelectric point position and electrokinetic potential values has been analyzed. The effect of silver localization on the electrokinetic characteristics of nanoparticles has been investigated. These characteristics have been compared with those of mechanical mixtures having the same mass ratios of the components.
