A cheap sodium ferric EDTA-derived material (EDTAFeNa-KB-HT1) was prepared via one-step pyrolysis of a complex of Ketjenblack EC-300J and inorganic-organic hybrid EDTAFeNa, which was employed as both nitrogen and ferric precursors. The EDTAFeNa-KB-HT1 was proved to be an iron and nitrogen co-doped Fe-N-C material with micro-mesoporous structure and large surface area. The EDTAFeNa-KB-HT1 exhibited high selectivity (80∼100%) towards oxygen reduction reaction for electrocatalytic synthesis of hydrogen peroxide (H₂O₂) concurrently with generation of large current density, which could be potentially a safe, efficient and environment-friendly fuel cell method for the scale production of H₂O₂.

通过Ketjenblack EC-300J与无机-有机杂化EDTAFeNa的复合物的一步热解制备了廉价的EDTA钠铁金属材料（EDTAFeNa-KB-HT1），该复合物同时用作氮和铁的前体。EDTAFeNa-KB-HT1被证明是一种铁和氮共掺杂的Fe-NC材料，具有微中孔结构和大表面积。EDTAFeNa-KB-HT1对氧还原反应具有很高的选择性（80％至100％），用于电催化合成过氧化氢（H ₂ O ₂），并产生大电流密度，这可能是安全，高效且环境友好的。 H ₂ O ₂规模化生产的友好燃料电池法。
