Apparatus and method for manufacturing continuous reactor type core-shell catalyst electrode

An apparatus for manufacturing a continuous reactor type core-shell catalyst electrode comprising:

• a main body an upper portion of which is opened and closed by attachment/detachment;
• reaction chambers which are disposed plurally in a line inside thereof, store reaction solution inside thereof, are equipped with counter electrodes, and a lateral portion of which is coupled with a reference electrode;
• a palladium sheet which is immersed in the reaction solution;
• a movable member which accommodates the palladium sheet and moves the accommodated palladium sheet to be immersed in the reaction solution;
• a moving path member which provides the movable member with a moving path;
• a power transmission member which transmits power to the movable member;
• 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.

A method of manufacturing a continuous reactor type core-shell catalyst electrode by using reaction chambers disposed in a circular shape comprising:

• a first step of reducing a palladium sheet by applying a voltage to an electrode immersed in a reaction solution when the palladium sheet is moved by a movable member and immersed in the reaction solution of the reaction chamber;
• a second step of coating the reduced palladium sheet with copper by injecting a copper precursor-containing solution into the reaction solution and then providing electric potential, which is higher than oxidation and reduction of copper, for the electrode;
• and
• a third step of coating the copper-coated palladium sheet with platinum by injecting a platinum precursor-containing solution into reaction solution when the copper-coated palladium sheet is moved by the movable member and immersed in the reaction solution of a reaction chamber different from the reaction chambers at the first and second steps.
