Template Free Preparation of Heteroatoms Doped Carbon Spheres with Trace Fe for Efficient Oxygen Reduction Reaction and Supercapacitor

Abstract

Dithiooxamide (DTO), an organic ligand, is used to synthesize a ZnDTO framework, which acts as a precursor for self-doping of heteroatoms in the presence of hemoglobin via carbonization process for S and N doped carbon (SNC) and Fe-SNC. The sphere shaped porous carbon particles having a graphene network exhibit excellent performance for energy conversion and energy storage applications.
