The Preparation and Electrochemistry of the Modified Electrodes by the Nano Silver-Zirconium Phosphate Composite Film

A novel composite material consisting of nano-colloidal silver and zirconium phosphate was synthesized and applied for the preparation of modified electrodes. The electrochemical property of the modified electrode was studied by the cyclic voltammetry. The nature of nano size particles of silver and the ability of zirconium phosphate to tune the potential were retained in this complex film. The ability of zirconium phosphate to adsorb neutral red and the redox reaction activity of neutral red were enhanced significantly in the composite film. The composite film modified electrode showed greater response. The composite film presents better mechanic strength and the modified electrode shows better stability.
