杂多酸(盐)是一类具有确定组成的含有氧桥的多核配合物,目前在理论和应用中研究得最多的是钼、钨杂多酸(盐),它们既具有配合物和金属氧化物的结构特征,又兼有酸性和氧化还原性能。分子量较大的钼、钨杂多酸阴离子呈笼状结构。鉴于它们的这些特点,钼、钨杂多酸(盐)在催化领域中的应用 Heteropolyacids (salts) are a class of polynuclear complexes containing oxygen bridges of definite composition. At present, the most studied in theory and application are molybdenum and tungsten heteropolyacid (salt), which have both complex and metal oxidation The structural characteristics of the material, but also both acidic and redox properties. Molecular weight of molybdenum, tungsten heteropolyacid anion cage-like structure. In view of these characteristics, the application of molybdenum, tungsten heteropolyacid (salt) in the field of catalysis
