Nitrogen and oxygen co-doped mesoporous carbons that can serve as metal-free electrocatalysts are synthesized via a novel synthetic route using milled rice as a precursor and colloidal silica as a template. The materials efficiently electrocatalyze the hydrazine oxidation reaction with only a small onset potential, while giving a high peak current density and showing good long-term stability.
