Highly Porous Chitosan-derived Nitrogen-doped Carbon Applicable for High-performance Gas Diffusion Oxygen Electrodes

A chitosan-derived nitrogen-doped carbon (NDC) with a well-designed pore structure is prepared by a novel activation process using ZnO and water vapor. The gas diffusion electrode comprising the obtained NDC for oxygen reduction exhibits higher performance than Pt/carbon black electrode in the current density range of 1-500 mA/cm(2).
