Template Synthesis of Ag@Fe-N-Doped Carbon Electrocatalyst for Oxygen Reduction Reaction in Alkaline Media

A simple template method is proposed for the synthesis of Ag nanoparticles embedded in Fe-N-C (Ag@FeNC) as excellent oxygen reduction reaction (ORR) catalyst. Firstly, Ag@Fe3O4 nanoparticles are synthesized and loaded onto graphene oxide to form the Ag@Fe3O4-GO template. The surface of the template...

Summary:A simple template method is proposed for the synthesis of Ag nanoparticles embedded in Fe-N-C (Ag@FeNC) as excellent oxygen reduction reaction (ORR) catalyst. Firstly, Ag@Fe3O4 nanoparticles are synthesized and loaded onto graphene oxide to form the Ag@Fe3O4-GO template. The surface of the template is then enveloped by polypyrrole. After pyrolysis at 850°C for 1 h, Ag@FeNC is synthesized and demonstrates excellent ORR catalytic activity in alkaline medium. Therefore, it provides a simple method for preparing metal@Fe-N-C hybrid catalysts.
