Abstract: A method for producing a catalyst for an electrochemical reaction that can be sized into fine particles while having a high specific surface area by using a carbon-based spacer in the catalyst synthesis process includes preparing a mixture by mixing a carbon-based spacer and a catalyst precursor and heat-treating the mixture.

Abstract: A refrigerator for drinks is provided. The refrigerator may include a cabinet having a storage compartment therein, and a dispenser nozzle disposed to be at least partially exposed outside the cabinet. A pump connection line being able to increase pressure in a drink container by delivering high-pressure air into the drink container and a tank connection line preventing oxidation of the drink in the drink container by delivering an unreactive gas into the drink container may be disposed in the cabinet. Accordingly, two functions of discharging a drink and preventing oxidation may be individually performed, so consumption of an unreactive gas may be reduced.

Abstract: A refrigerator for drinks is provided. The refrigerator may include a cabinet and a cooling guide transmitting coldness to a drink container stored in an erect state in the cabinet. Several coolers may be disposed for cooling guides and may cool the cooling guides, respectively, and dispenser nozzles may be disposed to be exposed outside the cabinet, whereby drinks may be dispensed. A surface of a cooling block facing a thermoelectric element of the cooler and a surface of the cooling block facing the cooling guide may have different areas.

Abstract: A refrigerator for drinks is provided. The refrigerator may have an open hole that is open upward, so a drink container may be inserted in an erect state in a cabinet through the open hole. An insertion guide connected to the open hole may be disposed in the cabinet and the width of the insertion guide may change in a height direction. Accordingly, a drink container may be guided by the insertion guide when being inserted into or taken out of the refrigerator for drinks.
