Co2 reforming catalyst, method of preparing the same, and method of reforming co2 using the catalyst

A method of modifying CO2, the method comprising:

• performing a catalytic reaction with a CO2 reforming catalyst according to the following Reaction Scheme 5,
• 3CH4+CO2+2H2O→4CO+8H2 [Reaction Scheme 5]
• the CO2 reforming catalyst including a catalyst metal and a porous carrier, the catalyst metal being at least one of Ni, Co, Cr, Mn, Mo, Ag, Cu, Zn, and Pd, the porous carrier supporting the catalyst metal such that a bonding surface of the catalyst metal conforms to a supporting surface of the porous carrier, the bonding surface of the catalyst metal being united with the supporting surface of the porous carrier by an alloy bond, the catalyst metal having a cross-section of a circular, elliptical, or oval shape, the cross-section defined by a plane extending through a center of the catalyst metal and extending perpendicularly to the supporting surface of the porous carrier, the catalyst metal having a height designated as h, the height being a vertical distance from an uppermost surface of the catalyst metal to the supporting surface of the porous carrier, the circular, elliptical, or oval shape of the cross-section having at least one of a radius designated as r, a major radius designated as ra, and a minor radius designated as rb, the major radius ra being greater than the minor radius rb, the height of the catalyst metal satisfying the relationship h<2r or h<2ra.
