Abstract

Bimetallic core-shell nanoparticles Co@Ni and Ni@Co and CoNi alloy ones have been prepared via polyol synthesis. Comparison of morphology, magnetic, and catalytic properties of the nanoparticles have revealed that the particles structure rather than the nickel/cobalt ratio determines their catalytic activity in the model reaction of p-nitrophenol reduction into p-aminophenol.
