摘要： A method for making a metal organic framework suspension is described herein. The method includes providing a hybrid material comprising a nano-crystalline metal organic framework comprising micropores and a mesoporous polymeric material comprising mesopores, wherein the nano-crystalline metal organic framework is homogeneously dispersed and substantially present only within the mesopores or void spaces of the mesoporous polymeric material; and wherein the hybrid material has a weight percentage of the metal organic framework in the range of 5-50% relative to the total weight of the hybrid material. The method includes contacting the hybrid material with a solvent in which the mesoporous polymeric material is soluble, thereby forming a polymeric solution in which the nano-crystalline metal organic framework is substantially homogeneously dispersed and suspended.

摘要： Disclosed in the present disclosure are a lithium adsorbent and a preparation method therefor. The lithium adsorbent has a porous structure, and includes an aluminum-based lithium adsorbent active material and a hydrophilic binder; and the lithium adsorbent has an average pore diameter ranging from 1 nm to 10 nm, a pore volume ranging from 0.65 ml/g to 0.8 ml/g, and a specific surface area ranging from 400 m2/g to 600 m2/g. The lithium adsorbent of the present disclosure has a specific average pore size ranging from 1 nm to 10 nm, lithium ions have a diameter of 0.3 nm, and the pore size of the lithium adsorbent of the present disclosure is three times or more greater than the diameter of the ions so that the lithium ions can quickly enter and exit pores. Therefore, the structure can ensure high adsorption efficiency and high desorption efficiency at a high flow rate, and allows desorption to be more concentrated than that of a general lithium adsorbent to reduce tailing, and can effectively improve the lithium production efficiency. Moreover, the product of the present disclosure has a pore size of less than 10 nm, allowing the lithium adsorbent to have a low dissolution loss rate and a long service life, and the lithium adsorbent of the present disclosure still has high adsorption efficiency and high desorption efficiency after 1000 cycles of adsorption and desorption.
