Abstract With the depletion of petrochemical energy and the greenhouse effect issues caused by petrochemical energy. It is imperative to develop a kind of fuel cell has the advantages of environmental-friendly, energy saving, and low waste emission, which has great potential in future. Therefore, it’s necessary to develop a composite material with low-cost, environmental-friendly, and good stability to replace the Pt-based electrocatalyst. In this research, we prepared the Mn,Ni-doped carbon nanotubes (Mn,Ni/NCNTs) by one-step in-situ method. The transition metal (Mn, Ni) nanoparticles were coated on the acidified-carbon nanotubes to prepare the precursor. After calcined at a certain temperature, the Mn,Ni/NCNTs composite was obtained successfully. The catalytic performance of the catalysts prepared by different transition metals and different calcination temperatures were systematically studied. The results showed the produced composites had layered tubular structure, large surface area, and possessed excellent stability and methanol resistance. This kind of composite is a promising catalyst in the future practical application.

Mn-Ni氧化物纳米粒子通过氮掺杂在碳纳米管上结合催化氧还原

摘要 随着石化能源的枯竭和石化能源引发的温室效应问题。开发一种具有环保、节能、废物排放低等优点的燃料电池势在必行，未来潜力巨大。因此，有必要开发一种低成本、环保、稳定性好的复合材料来替代Pt基电催化剂。在本研究中，我们通过一步原位法制备了 Mn,Ni 掺杂的碳纳米管 (Mn,Ni/NCNTs)。将过渡金属（Mn，Ni）纳米颗粒涂覆在酸化的碳纳米管上以制备前驱体。在一定温度下煅烧后，成功获得了Mn,Ni/NCNTs复合材料。系统研究了不同过渡金属和不同煅烧温度制备的催化剂的催化性能。结果表明，制备的复合材料具有层状管状结构，比表面积大，具有优异的稳定性和耐甲醇性。这种复合材料是未来实际应用中很有前景的催化剂。
