3-D Nanoporous Pt Electrode Prepared by a 2-D UPD Monolayer Process

A simple yet effective way is described to fabricate a nanostructured platinum electrode with extra high surface area. The fabrication process is the combination of the UPD monolayer and galvanic displacement in one electrochemical process and it is conducted in one medium and at the ambient temperature without using any toxic or corrosive electrolytes. The porous structure and roughness factor of the nanostructured Pt film can be controlled with the sweeping cycle of cyclic voltammetry (CV) easily. The nanoporous Pt deposit can enhance the response of the detection of glucose significantly an selectively without any enzyme incorporation. It is demonstrated that the nanostructured Pt film serves as a new electrode material in the application of nonenzymatic glucose detection.
