Electrochemical Preparation

Electrochemical deposition of polytyramine (PTy) was performed by cyclic voltammetry and it was observed that, in acidic media, 20 to 50 consecutive deposition cycles allowed us to obtain polymer coatings with good conductivity and high porosity. The polytyramine layers were used as a matrix for electrochemical deposition of platinum and the electrocatalytic activity for methanol oxidation of the composite material thus obtained was put in evidence.
