Synthesis of binary metal nanoparticles of Ru-Ni with core and shell structure

Binary metal nanoparticles of Ru-Ni were synthesized with core and shell nanostructures by flash pyrolysis. Ruthenium chloride and Nickel chloride were used as a binary mixture to generate the binary nanoparticles. SEM and TEM images confirmed the formation of eutectic metal deposits of less than 15 nm with Ruthenium forming the core and Nickel forming the shell and Ru-Ni binary metal core and shell nanostructure was obtained. Characterization of the nanoparticle size was achieved by fit to a log-normal distribution. X-ray images of the samples taken also confirmed the concentration of ruthenium more at the core of the particle.
