Polyoxometalates (POMs), a large family of anionic polynuclear metal-oxo clusters, have received considerable research attention due to their structural versatility and diverse physicochemical properties. Lacunary POMs are key building blocks for the syntheses of functional POMs due to their highly active multidentate O-donor sites. In this review, we have addressed the structural diversities of Ti/Zr-substituted POMs based on the polymerization number of POM building blocks and the number of Ti and Zr centers. The synthetic strategies and relevant catalytic applications of some representative Ti/Zr-substituted POMs have been discussed in detail. Finally, the outlook on the future development of this area is also prospected.
多金属氧酸盐(POMs)是一类多核金属氧簇阴离子,由于其结构的多样性和丰富的物理化学性质,引起了广泛的研究关注。缺位多金属氧酸盐是合成功能多金属氧酸盐的关键构建模块,因为它们具有高活性的多齿 O-供体位点。在本综述中,我们根据多金属氧酸盐构筑块的聚合度以及 Ti 和 Zr 中心的数量,讨论了 Ti/Zr 取代的多金属氧酸盐的结构多样性。详细讨论了一些代表性的 Ti/Zr 取代的多金属氧酸盐的合成策略和相关的催化应用。最后,还展望了该领域未来的发展前景。
