Novel Co-N-C hybrids were successfully fabricated via one-step pyrolysed soy milk with the aid of cobalt(II) nitrate in a synthetic process. Because of the formation of the Co-N-C structures, the resulting product showed excellent electrocatalytic activity for the ORR in alkaline electrolytes, potentially making Co-N-C a nonprecious metal cathode catalyst for ORR. The technique can also be scaled up easily and this research provides a great opportunity for industry to produce an eco-friendly carbon nanomaterial for fuel cells and other electrochemical energy devices.
通过在合成过程中借助硝酸钴一步热解豆浆成功制备了新型Co-N-C杂化物。由于形成了Co-N-C结构,所得产物在碱性电解质中对氧还原反应(ORR)表现出优异的电催化活性,这可能使Co-N-C成为用于ORR的非贵金属阴极催化剂。该技术还可以很容易地扩大规模,这项研究为工业生产用于燃料电池和其他电化学能量装置的环保型碳纳米材料提供了巨大机遇。
