NICKEL-BASED CATALYST FOR LOW TEMPERATURE CO OXIDATION PREPARED USING ATOMIC LAYER DEPOSITION AND APPLICATION THEREOF

摘要

The present invention relates to a nickel-based catalyst for oxidizing carbon monoxide, which is prepared by forming nickel oxide on the surface of a mesoporous support by one or more cycles of atomic layer deposition, and a use thereof.;The nickel-based catalyst for oxidizing carbon monoxide according to the present invention is stable at high temperatures because the size of the nickel oxide particles can be restricted to nanometer scales even at high-temperature conditions. In addition, the nickel-based catalyst exhibits catalytic reactivity for oxidation of carbon monoxide even at room temperatures. Additionally, the catalytic activity, which has been deactivated after conducting the catalytic reaction, can be regenerated through annealing and increased gradually through repeated annealing.
