Preparation method and application of defective aluminum-based metal organic framework material
The invention discloses a preparation method and application of a defective aluminum-based metal organic framework material, and relates to the field of metal organic framework material research. The preparation method comprises the following steps: mixing a first solution containing aluminum salt and a second solution containing 3, 5-pyrazoledicarboxylic acid, then adding a sodium hydroxide solid, and stirring until the sodium hydroxide solid is completely dissolved to obtain a mixed solution; reacting the mixed solution at a certain temperature for a certain time, and after the reaction is completed, naturally cooling the product to room temperature to obtain a precipitate; and finally, centrifugally drying the obtained precipitate to obtain the defective aluminum-based metal organic framework material. The yield of the defect type aluminum-based metal organic framework material prepared by the method is more than 50%. The structure of the defective aluminum-based metal organic framework material crystal is rough, a large number of defects exist on the surface, the water absorption performance is improved, and the material can be applied to water collection in an extremely-low-humidity environment.
本发明公开了一种缺陷型铝基金属有机骨架材料的制备方法及其应用，涉及金属有机骨架材料研究领域。将含铝盐的第一溶液和含3,5‑吡唑二甲酸的第二溶液混合，然后加入氢氧化钠固体，搅拌至完全溶解，得到混合溶液；然后将混合溶液在一定温度下反应一定时间，反应完成后将产物自然冷却至室温得到沉淀物。最后将所得沉淀物离心干燥，得到缺陷型铝基金属有机骨架材料。上述方法制备的缺陷型铝基金属有机骨架材料的产率在50％以上。缺陷型铝基金属有机骨架材料晶体的结构粗糙，表面存在大量缺陷，提高了吸水性能，使该材料能够应用于极低湿度环境下集水。
