| 英文摘要 | Development of non-noble metal cathode catalysts was a continuous hotspots of fuel cell research. In this work, the CoO nanorods/C with different mass content of CoO were prepared by hydrothermal method and were investigated as cathode catalysts in direct borohydride fuel cell. The CoO nanorods exhibited an average length about 1-2 mu m and an average diameter about 15 nm. The 10 wt% CoO nanorods/C achieved the best oxygen reduction reaction (ORR) activity compared to the 5 wt% CoO nanorods/C and 20 wt% CoO nanorods/C. The onset reduction reaction potential of the 10 wt% CoO nanorods/C catalyst toward ORR was 0.821 V (vs. reversible hydrogen electrode), and the number of electron transfer was about 4.01. The ORR on the catalyst was mainly based on an appropriate four-electron reaction pathway. The half-wave potential difference of the 10 wt% CoO nanorods/C after 5000 cycles was 26 mV, suggesting a good catalytic stability. The DBFC using the cathode catalyst achieved a maximum power density of 410 mW cm(-2) at 60 degrees C. The experimental results confirmed that the CoO nanorods/C had excellent catalytic performance in DBFCs. (C) 2019 Elsevier B.V. All rights reserved. |
