Abstract
The present invention concerns methods of forming metal-containing nanoparticles or oxide thereof, especially metal alloy nanoparticles. The method the steps of providing at least two different kinds of transition metal ion by providing at least two kinds of metal ion-containing compound; a heating step in which the at least two metal ion-containing compounds are subjected to a temperature of at least 300° C. to form the metal alloy nanoparticles; a cooling step comprising cooling the product of step b; and each metal ion-containing compound is a transition metal complex having ligands coordinated to a transition metal ion, the ligands being selected from the group consisting of glyoxime; a glyoxime derivative; salicylaldimine; and a salicylaldimine derivative. The preferred methods are solution-based methods. Products of the methods are also described, as are their uses as electrocatalysts, as well as uses of the metal ion-containing compounds for making nanoparticles.
