摘要
金属有机骨架(MOFs)经过二十多年的快速发展,已经合成了成千上万种,然而MOFs材料普遍具有较低的稳定性,在一定程度上限制了MOFs的发展。UiO-66的合成是MOFs材料稳定性的一个突破,其在催化领域的发展尤为迅速。本文首先介绍了理想及实际状态下UiO-66的结构特征,并说明了配体缺失导致的节点空位处的元素组成。然后综述了利用UiO-66特殊的结构特征或将其功能化用于催化反应的研究,包括节点空位、功能化节点空位、负载金属纳米颗粒、功能化配体等。最后,考虑到可以综合利用UiO-66的特殊结构,对UiO-66在未来多功能催化剂的设计合成领域所能发挥的作用进行展望。
Thousands of metal-organic frameworks(MOFs)have been synthesized after more than two decades of rapid development.However,MOFs generally have low stability,which limits the development of MOFs to some extent.The synthesis of UiO-66 is a breakthrough in the stability of MOFs materials,and its development in the field of catalysis is particularly rapid.This paper first introduces the structural characteristics of UiO-66 under ideal and actual conditions,and illustrates the elemental composition of the node vacancies caused by ligand loss.Then,the UiO-66 itself or their functionalization for catalytic reactions are reviewed,including node vacancies,functionalized node vacancies,supported metal nanoparticles,and functionalized ligands.Finally,considering the comprehensive utilization for the structure of UiO-66,the role of UiO-66 in the design and synthesis of multifunctional catalysts in the future is expected.
