A method for preparing a transition metal electrochemical catalyst according to an embodiment of the present disclosure includes dissolving a nitrogen precursor and a transition metal precursor in a polyol-based solvent so as to prepare a solution in which transition metal ions and free anions are coordinated, and mixing same with a support so as to prepare a mixture, igniting the mixture so as to carbonize the polyol-based solvent, thereby forming transition metal nanoparticles encompassed by carbon, performing heat treatment in order to carbonize remaining organic matter contained in the mixture, and removing, through acid treatment, impurities and transition metal nanoparticles not encompassed by carbon, and then removing remaining acid through washing and additional heat treatment, thereby a nanocatalyst having a structure in which a single-atom transition metal-nitrogen bonding structure and/or transition metal nanoparticles encompassed by carbon exist is synthesized.

Transition metal electrochemical catalyst prepared using ultrafast combustion method, and synthesis method therefor

An additive supply apparatus for a washing machine includes a cartridge configured to accommodate a liquid additive therein and discharge the additive through a discharge port formed at one side thereof, a discharge tube that is connected to the cartridge and defines a discharge path configured to guide the additive discharged from the cartridge, a check valve assembly interposed between the cartridge and the discharge tube and configured to selectively open or close the discharge tube and the discharge port of the cartridge depending on a change in pressure, a pump configured to generate a pressure to be provided to the check valve assembly, and a pressure tube configured to connect the check valve assembly and the pump and transmit the pressure generated from the pump to the check valve assembly. The check valve assembly has one end connected to the cartridge and another end connected to the discharge tube.

Additive supply unit and washing machine including the same
