摘　　要：合成了钛取代杂多硅钨酸盐Ｋ６ＳｉＷ１１ＴｉＯ４０·１６Ｈ２Ｏ（ＳｉＷ１１Ｔｉ），并用元素分析、红外光谱、紫外－可见光谱和１８３ＷＮＭＲ谱进行表征．对其溶液电化学性质进行了讨论．其还原过程包括钛的单电子还原和钨的双电子两质子加合过程．The titaniumsubstituted heteropolytungstosilicate K6SiW11TiO40·16H2O(SiW11Ti) was synthesized and characterized by elemental analysis, IR, UVVis and 183W NMR spectra. Its electrochemical behavior in aqueous solution has been discussed. Its reduction process involves an oneelectron reduction of Ti(Ⅳ) and a pair of twoelectron reduction of W(Ⅵ). It shows a good catalytic activity on the reduction of NO-2 in weak acid medium.
