英文摘要 | Exploring highly active, cost-effective and durable oxygen reduction reaction (ORR) electrocatalysts as substitutes for the rare platinum -based catalysts is of great significance in energy conversion and storage devices, such as alkaline fuel cells, metal-air batteries, etc. Herein, we fabricated a new type ORR electrocatalyst of Ni-Co nanocrystal alloy encapsulated in N-doped carbon nanotubes (NCNTs) through a facile, scalable route utilizing nickel acetate and cobalt chloride as metallic Ni and Co precursors, thiourea as a nitrogen and carbon source, respectively, under a Ni/Co atomic ratio of 3:7 at 700 degrees C. The obtained nanocomposite catalyst NiCo@NCNT-700 exhibited an outstanding ORR activity close to that of the state-of-the-art Pt/C catalyst and superior operational durability under alkaline conditions, which could be attributed to the co-contributions among the uniformly distributed Ni-Co alloy nanoparticles, graphitic NCNTs and the formation of Co-N species. This work provides a new insight for the rational design and development of efficient non-noble metal electrocatalysts by integrating electrochemically active units into the nanocomposite for challenging electrochemical energy-related technologies.
