杂多化合物以其特有的结构特征和物理化学性质,已经成为一类具有广阔应用前景的酸型、氧化还原型或双功能催化剂,在催化领域中越来越引人关注,它们被还原后,大多数呈现深蓝色,故习惯上称为“杂多蓝”(heteropoly blue),它在氧化还原催化、分析化学及光化学等方面显示出重要用途,迄今为止,有关Keggin结构杂多蓝的离析和性质研究有很多报道, Heteropoly compounds with its unique structural features and physicochemical properties, has become a broad application prospects of acid, redox or bifunctional catalyst, in the field of catalysis more and more attention, they are reduced, the large The majority appear dark blue, so it is customarily referred to as “heteropoly blue” (heteropoly blue), which shows important applications in redox catalysis, analytical chemistry and photochemistry. So far, the segregation and properties of heteropoly blue in Keggin structure There are many reports on research,
