  • Patent number: 10022709
    Abstract: Transition metal carbide, nitride, phosphide, sulfide, or boride nanoparticles can be made by transforming metal oxide materials coated in a ceramic material in a controlled environment. The coating prevents sintering while allowing the diffusion of reactive gases through the inorganic matrix that can then alter the metal nanoparticle oxidation state, remove oxygen, or intercalate into the lattice to form a carbide, nitride, phosphide, sulfide, or boride.
