Iranian Scientists Increase Efficiency of Proton Membrane Cells

Tehran, Iran | Posted on January 8th, 2013

They synthesized graphene through electrochemical methods, and they applied the reduction process simultaneously on graphene oxide and platinum.

In this research, graphene was firstly synthesized in a single stage without using environmental pollutants. Then, a nanocomposite of platinum nanoparticles and graphene was produced, and finally, its performance was studied in methanol oxidation.

Dr. Karim Kakayee, a member of the research team, explained how the nanocomposite of platinum nanoparticles and graphene was synthesized. "Graphene was firstly synthesized through an electrochemical single-stage process. Then, we reduced platinum nanoparticles on the bed of graphene oxide by using boron hydride and EDTA."

Results of the research show that the electrocatalytic activity of platinum nanoparticles in graphene bed in methanol oxidation process is almost twice as the commercial Pt/C. In addition, the starting potential of methanol oxidation on Pt/Graphene bed is less than that of Pt/C, and the kinetics of methanol oxidation in the new electrocatalyst is higher than that of the commercial sample, and it has higher signal per noise.

This catalytic powder is directly used in fuel cells, although graphene itself can be used in solar cells due to the lack of the application of pollutants in this method. According to Dr. Kakayee, the commercialization of graphene was one of the objectives of the research. In case the required support is provided, the production of graphene through this method can enter the industrial production stage.

Results of the research have been published in Journal of Power Sources, vol. 255. For more information, visit the detail of the research on pages 356-363.
