| titleOfInvention | Mesoporous praseodymium zirconium composite oxide and its preparation method |
| abstract | The invention relates to a mesoporous praseodymium zirconium composite oxide and a preparation method, which belong the technical field of chemical preparation. A molecular formula of the mesoporous praseodymium zirconium composite oxide is PrXZr1-XO2-d, wherein X is 0.05-0.95, d is 0-0.167, and the meso-structure is uniformly distributed on the surface and internal part of the mesoporous praseodymium zirconium composite oxide. According to the invention, a surfactant P123 or a triblock copolymer F127 or praseodymium zirconium metal salt is taken as a raw material, after dissolving by ethanol, the praseodymium zirconium composite oxide possessing meso-structure can be obtained through the steps of processing under hydrothermal or constant temperature constant humidity condition, drying and roasting. The mesoporous praseodymium zirconium composite oxide has the advantages of high specific surface area, high activity and high stability, and the technical scheme of the preparation method is simple, and is easy to industrially implement. |
