  • Formation of array nanoparticles during electrodeposition platinum on glassy carbon and dispersed carbon support

    In the present study, platinum was electrodeposited onto rotating disc electrode coated with Vulcan XC-72R Nafion suspension and uncoated smooth glassy carbon electrode from acidic solution of 5mМ H2PtCl6. The electrochemically active surface area of platinum particles obtained was determined by cyclic voltammetry and the structural characteristic of the particles was studied by scanning electron microscopy. The impact of current and time on the electrochemically active surface area of platinum particles electrodeposited on the carbon supports was also investigated and described in this paper. The present work is expected to be utilized and contribute to the improvement of electrochemically active surface area of platinum catalysts for low temperature fuel cells.
