锆基金属有机骨架(Zr-MOFs)具有丰富的结构类型、出色的热稳定性和化学稳定性以及多样化的功能，被认为是最具应用前景的新型晶态多孔骨架材料之一。通过一锅法及合成后修饰法等多种方法可将具有特定功能化官能团的有机配体引入Zr-MOFs体系，进而实现多组分锆基金属有机骨架(MC-Zr-MOFs)的构筑及对Zr-MOFs孔道环境的有效调控。MC-Zr-MOFs被广泛应用于气体吸附与分离、溶液相客体分子/离子吸附、多相催化、化学传感及光学材料等领域，展现出优异的性能。本文详细梳理了MC-Zr-MOFs的合成策略和应用研究的近期进展，并对其未来发展前景进行了展望。

An efficient interlocking process was developed, including acid leaching, co-precipitation, and heat treatment, to regenerate waste LiNi_0.5Co_0.2Mn_0.3O₂ (NCM523) materials. DL-tartaric acid and formic acid were used as leaching systems, and the leaching efficiencies of Li, Ni, Co, and Mn reached about 98%. The leaching solution was added to the oxalic acid solution for a co-precipitation reaction, and then the regeneration of the material was realized through heat treatment. The regenerated NCM523 material exhibited an excellent layered structure and uniform elemental distribution. When employed as a cathode material for LIBs, the regenerated NCM523 exhibited a discharge-specific capacity of 168.5 mAh·g^-1 at 0.1C (18 mA·g^-1), which is comparable to the performance of fresh NCM523. Furthermore, the regenerated NCM523 demonstrated a capacity retention of 93.09% after 100 cycles at 0.5C.
