摘要：

Carbon nanotube (CNT) electrode was selected to support lipid membranes. From electrochemical impedance results, lipid membranes of didodecyldimethylammonium bromide (DDAB) were identified to be formed on CNT electrode. Phosphopolyoxomolybdate (P2Mo18) was immobilized on DDAB modified CNT electrode through electrostatic adsorption and the properties of P2Mo18 were investigated by cyclic voltammetry (CV), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Additionally, CNT/DDAB/P2Mo18 electrode shows good stability in strong acidic medium (0.5 M H2SO4) and excellent electrocatalytic ability for the reduction of bromate and nitrite.
