Received Date: 11 September 1997
Revised Date: 6 January 1998

The titanium substituted heteropolytungstosilicate K₆SiW₁₁TiO₄₀°16H₂O (SiW₁₁Ti) was synthesized and characterized by elemental analysis, IR, UV-Vis and ¹⁸³W 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 NO₂^- in weak acid medium.
