| 英文摘要 | The importance of the oxygen reduction reaction (ORR) in fuel cells and high energy density metal-air batteries has attracted intense research interests in looking for low-cost ORR catalysts as substitutes for expensive and scarce Pt-based catalysts. N-doped graphene and carbon nanotubes prepared in a low-cost and scalable way have demonstrated their potential although the performance still needs to be improved. In view of the requirements for a high-performance ORR electrocatalyst, this work focused on developing the nanocomposites of N-doped reduced graphene oxide (N-rGO) and N-doped carbon nanotubes (N-CNT) as low-cost efficient ORR catalysts by integrating the advantages of abundant highly-active sites from N-rGO and a three-dimensional conductive network for efficient mass and electron transport from N-CNT. By optimizing the preparation method and dedicatedly tuning the composition, the much enhanced ORR activity and superior durability and tolerance to methanol were achieved for the self-assembled N-doped composite (N-rGO-CNT) at amass ratio of 1 : 5 rGO/CNT. Further improvement of the ORR electrocatalytic activity of the composite was also demonstrated by introducing iron into the composite. |
