Mechanochemical Synthesis of γ‑Fe2O3 Nanoparticles@N-Doped Mesoporous Carbons Derived from Biomass for Oxygen Reduction
A facile synthesis method via the ball-milling coupled with simultaneous carbonization and activation with KOH at different temperatures was employed to prepare γ-Fe2O3 nanoparticles-supported N-doped mesoporous carbons (denoted as γ-Fe2O3@N-doped CX-T) from a variety of biomass raw materials (sugar cane bagasse, coffe...
