摘要：

多金属氧簇（POMs）是一类由最高氧化态的前过渡金属（Mo、W、V、Nb和Ta）组成的分子基金属氧化物。纯无机POMs在极性溶剂中的高溶解度和低比表面积限制了其实际应用。有机?无机POMs和固载化POMs复合材料在催化、能量转换、储能和磁性等方面的应用前景引起了人们的广泛关注。对过渡金属/镧系元素修饰的有机?无机POMs和固载化POMs复合材料的设计合成进行了综述，并对POMs有机?无机杂化及其固载化进行了总结和展望。

Abstract:

Polyoxometalates (POMs) are molecular metal oxides composed of transition metals in their highes oxidation states (Mo,W,V,Nb,Ta). The high solubility and low specific surface area of pure inorganic POMs limi its practical applications in polar solvents. Due to the widespread applications of organic?inorganic hybrid POMs and immobilized POMs in the field of catalysis, energy conversion, storage and magnetism have attracted considerable attention.The design and synthesis of transition metal/Lanthanide modified organic?inorganic polyoxometalates and immobilized polyoxometalates composites are reviewed,and the practical applications of POMs with novel structures are summarized and outlooked.

Key words: Polyoxometalates, Organic?inorganic hybrid polyoxometalates, Immobilized polyoxometalates
