PURPOSE: The activation method of a transition metal nano catalyst and a transition metal nano catalyst activated thereby are provided to manufacture a transition metal nano catalyst in which a catalyst activation is improved regardless of the form of a catalyst with a simple process and obtain an economic effect by having a high reaction efficiency with the small amount of catalyst if the activated transition metal nano catalyst is used. CONSTITUTION: The activation method of a transition metal nano catalyst forms an oxide layer on the surface of a transition metal nano catalyst by chemically processing the surface of the transition metal nano catalyst. The transition metal nano catalyst is selected from a group consisting of rhodium, platinum, palladium, and iridium. The average diameter of the transition metal nano catalyst is 1 ~ 100 nm. The chemical surface process uses a method selected from a group consisting of an ultraviolet ray-ozone process or a plasma process. The ultraviolet ray-ozone process is performed by irradiating ultraviolet ray 150 ~ 300 nm in the ozone of 0.5 ~ 5 sccm. The plasma process performs the oxygen of 0.5 ~ 5 sccm with the power of 15 ~ 50W. The process is performed for 2 ~ 10 hours. |
