| 发明名称 | Perovskite catalyst and method of manufacturing the same | ||
| 摘要 | A method of manufacturing a perovskite catalyst composed of perovskite oxide includes mixing step, firing step and acid-treating step. In the mixing step, an A-site material and a B-site material are mixed at a stoichiometric ratio such that the A-site is increased, compared to that of a theoretical composition ABO3 of perovskite oxide in which a ratio of A-site and B-site is 1:1. In the firing step, the obtained mixed powder is fired. In the acid-treating step, the obtained fired powder is acid-treated with acid of pH 2 or more and less than pH 7. | ||

| 主权项 | 1. A perovskite catalyst manufactured by a method of manufacturing a perovskite catalyst, the method comprising the steps of: first, mixing an A-site material and a B-site material at a stoichiometric ratio to obtain a mixed powder of A-site material and B-site material, the A-site being produced from A-site material, the B-site being produced from B-site material, the stoichiometric ratio being such that the A-site is greater than an A-site of a theoretical composition ABO3 of perovskite oxide in which a ratio between A-site and B-site is 1:1; second, firing the obtained mixed powder to obtain a fired powder; and third, acid-treating the obtained fired powder with acid of pH 2 or more and less than pH 7. | ||
