Fe2O3 Embedded Nitrogen-doped Biomass Carbon as Electrocatalyst for the Oxygen Reduction Reaction
Journal of Physics: Conference Series(2021)
Abstract
Abstract Catalyst for ORR is important in the field of energy conversion. Previous research has shown that nanoparticle-embedded into N-doped carbon materials are a good ORR candidates. Here, Fe2O3/N-doped biomass carbon (named Fe2O3/N-bio-C) ORR catalyst via a pyrolysis process of mixture from the Heme precursor and biomass material (named poplar flowers). The as-synthesized electrocatalyst of Fe2O3/N-bio-C exhibits good electroactivity due to the formation of Fe2O3 nanoparticle active sites and abundant N-containing groups. The work points the way to synthesize the low-cost Fe-based N-doped biomass carbon ORR catalysts.
