英文摘要: N-doped carbon materials are extensively reported active toward the oxygen reduction reaction (ORR). Different from N-doped carbon, in this study, we report a kind of non-doped nitrogen, i.e., amide-groups, over carbon surface promoting the ORR activity of a CoOx/C-N composite. The amide-groups are successfully grafted over carbon surface (C-N) via a simple solvothermal route demonstrated by Fourier transform infrared spectra (FTIR) and X-ray photoelectron spectroscope (XPS). After loaded cobalt oxide nanoparticles of around 2 nm in average, the amide-group grafting carbon shows enhanced activity toward the ORR compared to its counterparts with carboxyl-group or the pristine carbon. For the first time, as known, the CoOx/C composite is used as the cathodic catalyst for the Zn-air battery, and the peak power density reaches up to 100-123 mW cm(-2), demonstrating the promising practical application in Zn-air battery. The enhanced ORR activity of the CoOx/C-N composite is probably related with the higher content of CoO in the composite surface induced by the amide group over carbon surface.
