Abstract
Oxygenelectrocatalyst is at the heart of many energy storage and conversiontechnologies including fuel cells, metal-air batteries and water electrolysis.The development of highly efficient and cost-effective oxygen electrocatalyststo replace noble metal-based catalysts is critical for the practicalapplication of these technologies. [1] Here we report a novel approach for thesynthesis of hollow framework of nitrogen-doped carbon nanotubes derived frommetal-organic frameworks (MOFs), demonstrating higher electrocatalytic activityand stability for oxygen reduction and evolution than that of commercial Pt/Ccatalyst. [2] The remarkable electrochemical properties are mainly attributedto thesynergisticeffect from compositions and robusthollow structure composed of interconnected crystalline N-doped carbonnanotubes. Our results demonstrate a new strategy to design and prepareMOFs-derived nanomaterials and represent new opportunities in developing highlyactive MOFs-derived catalysts as Pt alternatives in electrochemical energydevices.
