Abstract

The synthesis of mesoporous antimony-doped tin oxide films (meso ATO) was reported for a new type of electrode material that offers the unique combination of high surface area ordered mesoscale pores together with high electrical conductivity and high optical transparency. The meso-ATO was modified directly with Ru(bpy)2[bpy (COOH)2[PF6]2. The electrochemistry of the surface anchored dye on meso-ATO was studied by cyclic voltammetry. A button cell was fabricated for the ECL application, consisting of a dye-modified meso-ATO film as the working electrode separated from an ITO counter-electrode. The cell was filled with electrolyte and a prescribed quantity of sacrificial coreactant, which consisted of pH 7 phosphate buffer and tripropylamine (TPA). The result demonstrate that the meso-ATO film electrode with its high surface area and ordered pore network is a superior platform for potential ECL device applications.
