| titleOfInvention | Preparation method of porous lanthanum oxide |
| abstract | The invention discloses a preparation method of porous lanthanum oxide, which respectively weighs La (NO) with corresponding mass 3 )ยท6H 2 Preparing O and glycerol into solution with certain concentration with distilled water, and adding into the solutionAdding a certain amount of N-methyl-N-ethyl morpholine ionic liquid into a glycerol solution before mixing the two solutions, then adjusting the concentration, PH, heating time, heating temperature and other conditions of the added ionic liquid, and synthesizing the porous lanthanum oxide by a low-temperature combustion method. The preparation method is simple and easy to operate, the conditions are mild, and the prepared lanthanum oxide is superfine powder which is loose in texture, free of agglomeration and easy to crush, so that a new method is provided for preparing the porous lanthanum oxide. |
