A facile method prepared nitrogen and boron doped carbon nano-tube based catalysts for oxygen reduction
2017
Abstract In this paper, we designed a facile method to prepare nitrogen doped CNT (N-CNT), boron-doped CNT (B-CNT) and nitrogen, boron co-doped CNT (N,B-CNT) catalysts for oxygen reduction. The microstructures of the catalysts were characterized by Raman spectroscopy, X-ray diffraction (XRD), transmission electron microscope (TEM), and X-ray photoelectron spectroscopy (XPS). The results clearly showed the successful doping of nitrogen or/and boron. The cyclic voltammetry (CV), Tafel, linear scanning voltammetry (LSV) tests confirmed that the onset potentials and peak current intensities of oxygen reduction increased in the sequence of pure CNT
