| titleOfInvention | A kind of preparation method of cerium dioxide porous microspheres |
| abstract | The present invention relates to the preparation method of cerium dioxide porous microspheres, belong to technical field of new material preparation.The present invention includes three steps: (1) preparation EFI solution, by Ce (NOn 3 )n 3 6Hn 2 o and PVP is dissolved in DMF and forms EFI solution; (2) Electrospray ionization technology is adopted to prepare PVP/Ce (NOn 3 )n 3 complex microsphere, the external diameter of nozzle is 0.51mm, and internal diameter is 0.26mm, and voltage is 17kV, adopts perpendicular spray mode, and solidification distance is 20cm, and room temperature is 26 ~ 28 DEG C, and relative humidity is 40% ~ 60%; (3) CeO is preparedn 2 porous microsphere, by PVP/Ce (NOn 3 )n 3 complex microsphere, after 600 DEG C of insulation 4h, naturally cools to room temperature and can obtain CeOn 2 porous microsphere, diameter is 1 ~ 2 μm.The CeO of this kind of special appearancen 2 porous microsphere has good photocatalytic degradation capability to organic pollutant. |
