通过将介孔陶瓷与自组装单分子层化学相结合，实现了一类新型环保吸附材料的诞生。通过用镧系元素选择性配体封端的单层涂覆介孔陶瓷骨架，可以将高镧系元素结合亲和力与高负载容量（由载体的极高表面积产生）结合。该镧系元素选择性配体场通过将“硬”阴离子刘易斯碱与合适的协同配体以有利的螯合几何构型配对而产生。详细的合成，表征，镧系元素结合的研究，结合动力学，竞争实验和吸附剂再生研究进行了总结。
Through the marriage of mesoporous ceramics with self-assembled monolayer chemistry, the genesis of a powerful new class of environmental sorbent materials has been realized. By coating the mesoporous ceramic backbone with a monolayer terminated with a lanthanide-selective ligand, it is possible to couple high lanthanide binding affinity with the high loading capacity (resulting from the extremely high surface area of the support). This lanthanide-selective ligand field is created by pairing a "hard'' anionic Lewis base with a suitable synergistic ligand, in a favorable chelating geometry. Details of the synthesis, characterization, lanthanide binding studies, binding kinetics, competition experiments and sorbent regeneration studies are summarized.
