Highly active metal-free nitrogen-containing carbon catalysts for oxygen reduction synthesized by thermal treatment of polypyridine-carbon black mixtures. Electrochemistry communications, 13(6), 593-596.https://doi.org/10.1016/j.elecom.2011.03.0181388-2481https://nru.uncst.go.ug/handle/123456789/5290A straight-forward method for the synthesis of metal-free catalysts for oxygen reduction by thermal treatment of a mixture of poly(3,5-pyridine) with carbon black in helium is reported. The catalyst was characterized by X-ray diffraction and photoelectron spectroscopy, cyclic voltammetry and rotating disk electrode measurements. The new catalyst exhibited remarkable activity similar to Pt-based catalysts in alkaline media.enOxygen reduction; Metal-free catalysts; Thermal treatment; PolypyridineArticle
