Abstract

The Multicomponent heteropoly compounds [Me4N]3 + x[PVxMoyW12-x-yO40]. n(H2O) with Keggin structure have been synthesized, and have been characterized by FTIR and NIR FT-Raman. The vibrational regularity of oxygen-containing bonds (P-Oa, M = Od, M-Ob-M and M-Oc-M) in these heteropoly compounds have been studied. The vibrational frequencies nu as (M = Od) and nu as (M-Ob-M) was shown to prove the reason why the acidity of the heteropoly compounds descended and the oxidization increased by the substitution of V atoms.

摘要

合成了具有Keggin结构的多组分杂多化合物[Me4N]3 + x[PVxMoyW12 - x - yO40]. n(H2O)，并通过傅里叶变换红外光谱（FTIR）和近红外傅里叶变换拉曼光谱（NIR FT - Raman）对其进行了表征。研究了这些杂多化合物中含氧化合物键（P - Oa、M = Od、M - Ob - M和M - Oc - M）的振动规律。通过V原子取代，展示了振动频率νas（M = Od）和νas（M - Ob - M）以证明杂多化合物酸度下降和氧化增加的原因。
