Synthesis of Bimetal Fe–Pb Janus Nanoparticles via the Electric Explosion of Iron and Lead Conductors

The present work shows the ability to synthesize bimetal Janus nanoparticles of immiscible iron and lead metals via the electric explosion of two conductors. The electric characteristics of the explosion of Fe and Pb conductors are studied, and the dispersion/phase composition of nanoparticles, as well as the elemental distribution in nanoparticles, is comprehensively analyzed. Finally, the mechanism of the formation of Fe–Pb Janus nanoparticles under the electric explosion of conductors is proposed as well.
