“…G-IIP-3 exhibits high adsorption capacity for Gd(III) (181.75 mg/g) and a short equilibrium time of 30 min, while still maintaining high selectivity even in the presence of interfering ions [ 82 ]. Zhao et al used a certain amount of ZrOCl 2 -8H 2 O, H 1 (1,2,4-benzenetricarboxylic acid), and H 2 (1,2,4,5-benzenetetracarboxylic acid) mixed at room temperature to obtain nanoporous metal–organic frameworks (UiO-66-H 1 /H 2 -a) with a high adsorption capacity of up to 150–250 mg/g for a wide range of rare-earth ions (including Sm (III), Eu (III), Gd (III), Tb (III), Dy (III), Ho (III), Er (III), Tm (III), and Yb (III)) [ 96 ]. Zr-O clusters all play a key role in the adsorption process of rare earths, which provides a new research idea for the application of Zr-O clusters in the synthesis of adsorbent materials.…”

The exceptional photoelectromagnetic characteristics of rare-earth elements contribute significantly to their indispensable position in the high-tech industry. The exponential expansion of the demand for high-purity rare earth and related compounds can be attributed to the swift advancement of contemporary technology. Nevertheless, rare-earth elements are finite and limited resources, and their excessive mining unavoidably results in resource depletion and environmental degradation. Hence, it is crucial to establish a highly effective approach for the extraction and reclamation of rare-earth elements. Adsorption is regarded as a promising technique for the recovery of rare-earth elements owing to its simplicity, environmentally friendly nature, and cost-effectiveness. The efficacy of adsorption is contingent upon the performance characteristics of the adsorbent material. Presently, there is a prevalent utilization of porous adsorbent materials with substantial specific surface areas and plentiful surface functional groups in the realm of selectively separating and recovering rare-earth elements. This paper presents a thorough examination of porous inorganic carbon materials, porous inorganic silicon materials, porous organic polymers, and metal–organic framework materials. The adsorption performance and processes for rare-earth elements are the focal points of discussion about these materials. Furthermore, this work investigates the potential applications of porous materials in the domain of the adsorption of rare-earth elements.

“…6 Because the solid adsorbent is easily separated from the liquid phase by filtration, it can potentially be recycled multiple times and eliminate the use of organic solvents, reducing the overall cost of extraction. Many solid adsorbents have been explored for REE capture, including silica, 7-10 zeolites, [11][12][13][14] metal-oxides, 15,16 organic polymers, [17][18][19][20] metal-organic frameworks, [21][22][23][24] and graphene oxides. [25][26][27][28] However, the existing materials tend to lack either the required efficiency or customizable molecular functionality and, oftentimes, cannot be easily recycled.…”

Rare-earth elements (REEs) are present in a broad range of critical materials. The development of solid adsorbents for REE capture could enable the cost-effective recycling of REE-containing magnets and electronics. In this context, covalent organic frameworks (COFs) are promising candidates for REE adsorption due to their exceptionally high surface area. Despite having attractive physical properties, COFs are heavily underutilized for REE capture applications due to their limited lifecycle in aqueous acidic environments, as well as synthetic challenges associated with the incorporation of ligands suitable for REE capture. Here, we show how the Ugi multicomponent reaction can be leveraged to post-synthetically modify imine-based COFs for the introduction of diglycolic acid (DGA) moiety, a promising scaffold for REE capture. The adsorption capacity of the DGA-functionalized COF was found to be more than 40 times higher than that of the pristine imine COF precursor and more than three times higher than that of the next-best reported DGA-functionalized solid support. This rationally designed COF has appealing characteristics of high adsorption capacity, fast and efficient capture and release of the REE ions, and reliable recyclability, making it one of the most promising adsorbents for solid-liquid REE ion extractions reported to date.
