  • Patent number: 11655552
    Abstract: In an aspect, a method of making a composite core-shell nanoparticle comprises forming a nanoparticle core comprising nickel oxide or iron oxide via thermal decomposition of a nickel complex or an iron complex; and forming an oxide shell over the core, the oxide shell comprising nickel, iron or a mixture thereof. In another aspect, a method of making composite nanoparticles comprises providing a mixture comprising nickel complex and iron complex; and thermally decomposing the nickel and iron complexes to provide the composite nanoparticles comprising (Ni,Fe)Ox alloy. In yet another aspect, a composition comprises composite nanoparticles, the composite nanoparticles including a nickel oxide core and oxide shell, the oxide shell comprising a mixture of nickel and iron.
    Type: Grant

  • Patent number: 11131032
    Abstract: Metallic nanoparticles and related methods of making and using the same are described herein. An aqueous synthesis method is used to create nanoparticle cores comprising alloys of two or more metals at varying metal:metal molar ratios. In some embodiments, the nanoparticle cores described herein form a homogeneous metal alloy. Alternatively, the nanoparticle cores form a heterogeneous metal alloy. The synthesis method can further comprise forming mixed metal oxide shells on the nanoparticle cores.
