| titleOfInvention | A kind of lanthanum modified large mesoporous silicon film and its preparation method and application |
| abstract | The invention belongs to the field of material preparation technology and separation technology, and relates to a preparation method of a lanthanum-modified large mesoporous silicon membrane and an application of phosphorus adsorption in water bodies. The present invention uses natural biomass cellulose nanocrystals as a template, tetramethoxysilane as a silicon source, and adopts a solvent volatilization self-assembly method to prepare a CNCs/silicon dioxide composite film, and then removes the CNCs template by an acid washing method to form a large mesoporous Silicon oxide film, and then lanthanum is modified on the surface of the large mesoporous silicon film by ethanol evaporation followed by calcination. The phosphoric acid in the water body is adsorbed by the oscillation method, which has excellent adsorption performance. Advantages of the present invention: the lanthanum-modified large mesoporous silicon membrane is obtained by a simple preparation method. Because the mesoporous structure is relatively large, about 20 nm, it is beneficial to the later surface modification, and it is not easy to cause mesopore blockage, and has a larger lanthanum loading capacity, thereby It has a large adsorption capacity, and the material is green and environmentally friendly. Compared with powder materials, membrane adsorbents are recyclable and easy to reuse. |
