Abstract

Article history: Here, a new approach for the synthesis of phosphine-functionalized graphene oxide (GO-PPh ) was Received 8 April 2017 developed. Using a simple method, diphenylphosphine group was linked to the hydroxyl group of OH- Received in revised form 30 July 2017 functionalized graphene that existing at the graphene surface. The electrochemical activity of GO-PPh Accepted 1 August 2017 for electrochemical oxygen reduction was checked. The results demonstrated that the new carbon hybrid Available online 18 August 2017 material has a powerful potential for electrochemical oxygen reduction reaction (ORR). Moreover, GO- PPh as an electrocatalyst for ORR exhibited tolerance for methanol or ethanol as a result of crossover Keywords: effect. In comparison with commercial Pt/C and Pt/rGO electrocatalysts, results showed that GO-PPh has Oxygen reduction reaction a much higher selectivity, better durability, and much better electrochemical stability towards the ORR. Graphene oxide The proposed method based on GO-PPh introduce an efficient electrocatalyst for further application in Electrocatalyst fuel cells. © 2017 Elsevier B.V. All rights reserved. 1.
