Title

Evaluation of the influence of reduced graphene oxide (RGO) on improvement of Cu-MOF performance as electrocatalyst for oxygen reduction reaction in fuel cells

Pages

  83-99

Abstract

 The main target of this investigation is to synthesize several non-metallic Electrocatalysts with desirable performance and suitable price, for Oxygen reduction reaction at cathode side. For this purpose, five Electrocatalysts including graphene oxide (GO), nitrogen and sulfur doped graphene oxide (NS-RGO), copper Metal organic framework (Cu-MOF), 6% GO-Cu-MOF, and 8% NS-RGO-Cu-MOF are synthesized by hydrothermal method. In continue, in order to investigate the structure, activity, performance of synthesized electro catalysts, physical and electrochemical tests are employed, and obtained results are compared to the commercial 20% Pt/C. According to the physical tests outcomes, the structure of the synthesized Electrocatalysts is uniform, and the layering is correctly performed. Besides it was found that the size of Electrocatalysts is about of nanometer. Based on the electrochemical tests, amongst the synthesized Electrocatalysts, 8% NS-RGO-Cu-MOF has the best chemical activity. The onset potential of this catalyst is obtained by-0. 06 V vs Ag/AgCl. Also, the peak associated with Oxygen reduction reaction is shown in-0. 08 V, which the current density in this voltage is-4. 8 mA/cm2. Besides, the number of transferred electrons (n) for 8% NS-RGO-Cu-MOF is computed to be 3. 53, which indicates the reaction occurrs near to the 4 electron pathway. The onset potential of 6% GO-Cu-MOF is gained by-0. 11 V vs Ag/AgCl.
