Claims20
A copper-based core-shell nanoparticle comprising
- a core comprising Cu;
- and
- a shell comprising at least one noble metal.
The copper-based core-shell nanoparticle of any one of claims 1 to 10 having a diameter of about 5 nm to about 80 nm.
A process of forming the copper-based core-shell nanoparticle comprising
- mixing a Cu nanoparticle composition comprising an amine and a noble metal composition comprising a phosphine at a temperature of about 125° C. to about 155° C. to obtain a mixture;
- and
- cooling the mixture to obtain the copper-based core-shell nanoparticle dispersed in the amine.
A process of forming a Cu nanoparticle comprising
- mixing a Cu source and an amine at a temperature of about 200° C. to about 270° C. under an inert atmosphere to obtain a mixture;
- and
- cooling the mixture to form the Cu nanoparticle dispersed in the amine.
