Method for manufacturing catalyst for capture and conversion of carbon dioxide

A method of manufacturing a catalyst for capture and conversion of carbon dioxide, comprising:

• (a) preparing an oxide fine powder and a metal fine powder having an average size of 0.5 to 5 μm by pulverizing a oxide powder and a metal powder;
• (b) preparing a crystallized synthetic zeolite by adding an alumina-based raw material, a silica-based raw material, and sodium hydroxide to a reactor and stirring at 30° C. to 70° C. for 1 to 10 hours;
• (c) mixing a first alkaline solution after adding the oxide fine powder to the crystallized synthetic zeolite at predetermined time intervals and stirring;
• (d) adding the metal fine powder at predetermined time intervals and stirring after mixing a second alkaline solution with a mixture of step (c);
• and
• (e) obtaining a catalyst for capture and conversion of carbon dioxide by extracting only a liquid portion after mixing a third alkaline solution with a mixture of step (d), stabilizing for 40 to 50 hours,
