由多酸前驱体制备的钼基复合纳米材料的研究进展

Research Progress of Molybdenum Matrix Composite Nanomaterials Prepared by Polyoxometalates

多金属氧酸盐作为一类优秀的无机—有机建筑单元,因其具有丰富的结构组成、无与伦比的理化性能可广泛应用于药学、磁学、光电等领域。钼氧簇多酸盐作为多金属氧酸盐的一类重要的分支,由于具有丰富的钼源、碳源,近年来常被用作前驱体,可通过一步煅烧法制备出多样的钼基复合纳米材料,为以金属—有机框架(MOFs)为前驱体制备其他多级结构纳米金属化合物提供理论基础,特别是广泛应用于医学检测领域意义重大。

Polyoxometalates,an excellent inorganic-organic building unit,gets widely used in pharmaceutical,magnetic,photoelectric fields because of its rich structural composition,incomparable physical and chemical properties.Molybdenum oxygen cluster,which is an important branch of polyoxometalates,is often used as a kind of precursor due to its abundant molybdenum and carbon sources in recent years.based on which,various molybdenum-based composite nanomaterials can be prepared by one-step calcination.The practice can provide theoretical basis for preparing other multilevel nanostructured metal compounds by taking metal-organic framework(MOFs)as the precursor,and can be widely used in the field of medical detection;thus,the research progress is of great significance.
