摘要： The present disclosure is related to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst and, more specifically, to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst comprising steps of: nitridation-treating a transition metal precursor core and noble metal precursor shell particles in the presence of a gaseous nitrogen source; or forming a transition metal precursor core and noble metal precursor shell particles, by means of a liquid nitrogen source, and at the same time allowing the nitrogen source to bond with the transition metal precursor and thus allowing nitridation treatment. Therefore, the present disclosure allows a high nitrogen content in the core and thus enables a prepared catalyst to have excellent durability, a small average particle size and high degree of dispersion and uniformity, and thus to be suitable for the fuel cell field.

摘要： The present disclosure provides an apparatus and a method for manufacturing a continuous reactor type core-shell catalyst electrode, which may manufacture a large amount of continuous reactor type core-shell catalyst electrodes by improving coating efficiency of shell metal by using reaction chambers disposed in a circular shape or in a line. The apparatus for manufacturing a continuous reactor type core-shell catalyst electrode according to one exemplary embodiment of the present disclosure includes: a main body which is provided with a fixed shaft inside thereof and an upper portion of which is opened and closed by being detached from or attached to the fixed shaft; reaction chambers which are disposed plurally in a circular shape inside the main body, store reaction solution inside thereof, are equipped with movable members and counter electrodes, and a lateral portion of which is coupled with a reference electrode; a power transmission member which transmits power to the movable member; a palladium sheet which is moved by the movable member and immersed in the reaction solution as the movable member moves downward; a power supply which applies a voltage to the electrodes; and a solution injection member which injects a copper precursor-containing solution or a platinum precursor-containing solution into the reaction solution.
