摘要:

以C点、NH₃H₂O和Co(Ac)₂6H₂O为原料,用溶剂热方法制备了(Co, N)/C纳米催化剂。结果表明,催化剂多元掺杂比无掺杂或单一掺杂具有更好的氧还原催化活性,其氧还原起峰电位为-0.08 V,峰电位为-0.165 V,接近Pt-C(20% Pt)催化的起峰电位(-0.068 V);在该过程中氧还原转移电子数为3.59,接近一级反应动力学(转移电子数=4),中间产物H₂O₂的含量约25%。甲醇对(Co, N)/C催化剂催化能力的影响较小,循环催化10 h后其催化性能只下降8.8%,明显优于Pt-C在甲醇中的催化稳定性(下降37.9%)。N-(C)₂ ,C-N-C 以及 Co-C键都是催化剂的主要活性单元,纳米Co₃O₄颗粒可协同提高催化剂的催化能力。

Abstract：

Nano-catalyst of (Co, N)/C has been successfully synthesized by solvothermal method using Co(Ac)₂, NH₃H₂O and nano-carbon powder as starting materials. The results show that the oxygen reduction reaction (ORR) activity of (Co, N)/C is better than that of single nitrogen-doped or cobalt-doped nano-carbon powder in terms of the onset potential (-0.08 V) and peak potential (-0.165 V), which is comparable to the commercial catalyst Pt-C. The electron-transferred number of (Co, N)/C for ORR is about 3.59, which is close to the first order reaction kinetics of ORR (n=4). The intermediate product of H₂O₂produced from the ORR takes up about 25%. The (Co, N)/C catalyst also exhibits better methanol durability and stability comparing to the commercial Pt-C (20% Pt). Bonds of N-(C)₂, C-N-C and Co-C are the main active units of the catalyst and Co₃O₄ nano-particles can cooperatively improve the ability of catalyst.

Key words： metal-air batteries (Co,N)/C nano catalyst ORR onset potential doping
