基于多金属氧酸盐和贵金属的纳米复合材料的研究进展

摘要

基于多金属氧酸盐和贵金属纳米粒子的纳米复合材料,既具有多金属氧酸盐(POMs)可调控的多样结构、丰富的组成、高的电荷密度及可逆的氧化还原性,又具有贵金属纳米材料良好的生物相容性、高的光学活性和催化活性等特性,这些性质使基于POMs和贵金属纳米的复合材料能够应用于催化、生物医药、生物传感等领域.本文作者主要论述近年来基于多金属氧酸盐和贵金属的纳米复合材料的合成、性质及应用的研究现状,并对其前景进行展望.%Nanocomposites based on polyoxometallates and noble metal nanoparticles not only possesses diverse structure,rich composition,high charge density and reversible redox activity regulated of poly-oxometalates (POMs),but also have good biocompatibility,high optical activity,catalytic activity and other features of noble metal nanomaterials. These properties make the composites based on POMs and noble metal nanomaterials suitable for catalysis,biomedicine,biosensing,etc. The synthesis, proper-ties and applications of the nanocomposites based on POMs and noble metals in recent years are dis-cussed,and the prospect is predicted in this review.
