Abstract
Heteropoly acid H4SiW12O48 (denoted as SiW12) was assembled with the mesopo rous materials MCM-41 modified with 3-aminopropyltriethoxysilane (APTES) (d enote MCM-41((m))). The electrochemical behavior of SiW12/MCM-41((m)) compl exes-based electrode indicated SiW12 anion was adsorbed by MCM-41((m)). In MCM-41((m)) electrode, large voltammetric waves, showing that the electrost atic bound ions adsorbed in MCM-41((m)) were electrochemically active. The potential application as amperometric sensors for nitrite is anticipated.
