英文摘要	Low-cost and highly active catalysts for oxygen reduction reaction (ORR) were of great importance to the development of fuel cell. Herein, we presented a novel N/B co-doped carbon as cost-effective and stable ORR catalyst from renewable biomass. The as-prepared carbon showed an interesting hollow tube morphology that derived from its precursor. The N/B co-doped sample (NB-HCT) possessed bigger electrochemical active area (296.4 m(2) g(-1)), and also contained much more ORR active-N/B species than those of single N or B doped carbon. Notability, the on-set potential and half-wave potential of NB-HCT were 0.929 V (vs. RHE) and 0.810 V (vs. RHE), respectively, which were much more positive than others and even comparable to Pt/C, revealing it had distinct ORR activity. Remarkably, the superior ORR activity of NB-HCT could be mainly ascribed to the synergistic effect of ORR active-N and B-C, which might result in the possible formation of high-active B-C-N nanostructure. Therefore, NB-HCT should be one of promising ORR catalysts to alternative precious Pt/C and promote the development of fuel cell. (C) 2017 Elsevier Ltd.
