Abstract
A method for preparing coated metal nanoparticles, each nanoparticle comprising a core constituted of at least one metal M and a layer constituted of at least one polymer, the layer coating the metal core. The method comprises the steps: (a) preparing a solution A comprising the at least one metal M in the form of cations M, n being an integer comprised between 1 and 3, each metal M being a transition metal of atomic number comprised between 21 and 30, a polyol, and a noble metal salt; (a) preparing a solution B comprising at least one organic monomer of the at least one polymer, in an organic solvent; (b) mixing solutions A and B, this mixture being heated to the boiling temperature of the polyol; and (c) recovering the coated metal nanoparticles.
