Perovskite Oxide Catalyst Having Improved Oxygen Catalytic Activity and Preparation Method Thereof |
| abstract |
Disclosed is a catalyst having a perovskite structure in the form of ABO 3 , in which the number of ion moles at the A site has an excess ratio compared to the number of ion moles at the B site. The present invention exhibits an oxygen catalytic activity improved by about 3 times in an oxygen evolution reaction and by about 40% in an oxygen reduction reaction, compared to those of an existing LaNiO 3 perovskite catalyst. Further, since the metallic conductivity is not significantly changed compared to the existing LaNiO 3 perovskite oxide, there is an advantage in that a carbon support need not be used when the present invention is used as a catalyst in a battery positive electrode. |
