CO₂reforming catalyst, method of preparing the same, and method of reforming CO₂

摘要

A CO2 reforming catalyst may include at least one catalyst metal supported in a porous carrier. The at least one catalyst metal may include a transition metal (e.g., Ni, Co, Cr, Mn, Mo, Ag, Cu, Zn, and/or Pd). Each particle of the at least one catalyst metal may be bound with the porous carrier in a form of an alloy. The porous carrier may form a rod-shaped protruding portion around the catalyst metal particle.

1. A method of preparing a CO2 reforming catalyst, comprising:
immersing a porous carrier in a precursor solution of at least one catalyst metal to obtain an immersed carrier, the at least one catalyst metal including a transition metal; drying the immersed carrier to obtain a catalyst-carrier complex in which at least one catalyst metal particle is supported on the porous carrier; firing the catalyst-carrier complex under a presence of nitrogen (N2) or hydrogen (H2) gas to obtain a fired complex; purging the fired complex with inert gas to obtain a purged complex; reducing the purged complex to obtain a reduced complex; immersing the reduced complex in water to obtain a water-immersed complex; and reducing the water-immersed complex to obtain the CO2 reforming catalyst.
