Abstract:
Iranian nano-researchers achieved synthesis of an electrode requiring a minimum use of expensive metal, palladium, utilized in fuel cells and sensors.

Low-Cost Electrode Produced by Iranian Nano-Scientists

Iran | Posted on February 14th, 2010

The researchers at University of Isfahan managed to prepare an electrode from gold with acceptable oxygen reduction electro-catalytic ability and coated its surface with least possible amount of palladium use.

"First, nanoporous gold electrode was synthesized through anodizing method. Then, the surface of the electrode was coated by palladium applying under-potential deposition and spontaneous metal replacement. To describe in more detail, a relatively positive thermodynamic potential was applied to the nanoporous gold electrode initially to be covered with a single layer of copper," Effat Nekouyee Fard, a member of the research group said to the Iran Nanotechnology Initiative Council.

"Afterwards, the electrode was placed in palladium solution to trigger the spontaneous metal replacement process which ultimately leads to the complete replacement of copper by palladium," she added.

Such reduced use consumption of palladium has led to a considerable cut-down in the production cost of the mentioned electrode.

Nekouyee Fard described the fuel cell and sensor related industries as the main consumer of the prepared electrode, and expressed the hope that their group would be able to replace gold with less valuable counterparts as electrode bases in their future researches.
