In this work we analyze the influence of process parameters such as concentration of platinum and number of applied cycles in electrodepositing process on the catalytic activity of nanoplatinum electrocatalyst, fabricated by potentiocyclic electrodeposition to glucose oxidation reaction. Corresponding electrocatalyst were characterized by cyclic voltammetry and the surface texture of electrocatalyst was characterized by scanning electron microscopy, SEM image shows that the platinum elctrocatalyst have a spherical structure in nano scale. Electrodes with high roughness factor are obtained particularly when high platinum ion concentrations (2 mmol L−1 Pt, roughness factor 760 cm2}), and 75 cycles were applied during fabrication. Enhancing the catalytic activity of these electrocatalysts shows that changing the above process parameters reduces the polarization happened in the concentration region.
