MANUFACTURING METHOD OF CATALYST FOR REDUCING CARBON DIOXIDE AND OXYDIZING FORMIC ACID CATALYST FOR REDUCING CARBON DIOXIDE AND OXYDIZING FORMIC ACID MANUFACTURED BY THE SAME

摘要

According to an embodiment of the present invention, provided is a method for manufacturing a catalyst for reducing carbon dioxide and oxidizing formic acid, which comprises the following steps: preparing an electroplating solution containing a palladium precursor solution, an indium precursor solution and a support electrolyte; immersing a three-electrode terminal or a two-electrode terminal including a working electrode in the electroplating solution; forming a palladium-indium composite catalyst on the working electrode surface by applying voltage to the working electrode; and heat-treating the palladium-indium composite catalyst. Provided are a catalyst having activity in both reactions of reducing the carbon dioxide to formic acid or formic acid ion, and oxidizing the formic acid to carbon dioxide, and a manufacturing method thereof.
