  • Patent number: 11390535
    Abstract: The disclosure relates to a co-current co-precipitation method of CoNiO2 thermistor powders. The method comprises the steps of mixing, stirring, precipitating, aging, suction filtration, washing and drying firstly using nickel nitrate and cobalt nitrate as raw materials to obtain cobalt hydroxide, and then calcining in a tubular furnace at an inert atmosphere to prepare CoNiO2 nano powders. The method has the advantages of simple operation, low cost, short cycle, high yield and no environmental pollution, and further oxidization of the CoNiO2 nano material into NiCo2O4 thermistor powders can be effectively avoided through selection and adjustment of calcination process parameters and inert atmosphere. A high-precision, fast-response and small-volume temperature sensor material can be prepared from CoNiO2 thermistor powders obtained by the method of the disclosure.

  • Patent number: 9272334
    Abstract: Methods of synthesizing platinum-nickel-alloy nanoparticles and supported catalysts comprising the nanoparticles are provided. The methods may comprise forming a reaction mixture in a reaction vessel; heating the reaction mixture sealed in the reaction vessel to a reaction temperature; maintaining the temperature of the reaction vessel for a period of time; cooling the reaction vessel; and removing platinum-alloy nanoparticles from the reaction vessel. The reaction mixture may comprise a platinum precursor, a nickel precursor, a formamide reducing solvent, and optionally a cobalt precursor. In some embodiments the reaction temperature is at or below the boiling point of the formamide reducing solvent, such as from about 120° C. to about 150° C., for example. The platinum-alloy nanoparticles provide favorable electrocatalytic activity when supported on a catalyst support material.

    Abstract: Methods of forming monodispersed core-shell nanoparticles are provided. A cobalt(II)-ligand component, a metal(II)-ligand component, an organic reducing agent, and a capping agent can be added to an organic solvent to form a reaction mixture. The reaction mixture is then heated to a dissolving temperature while under a gas (e.g., including methane) such that the reaction mixture becomes a reaction solution while stirring at the dissolving temperature. The reaction solution is then be heated to a reaction temperature (e.g., about 200° C. or more) while under the gas to form the core-shell nanoparticles, and the core-shell nanoparticles can be collected from the reaction solution.
