Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Figure 2. Structure characterization of the CoN@OCNT catalysts. (a) HAADF-STEM image of the CoN@OCNT. (b) Co K-edge XANES spectra of the CoN@OCNT and reference samples. (c) Linear fit of Co valence versus Co K-edge energy position. (d) FT k2-weighted and fitting extended XAFS (EXAFS) spectra of the CoN@OCNT and reference samples. (e) Wavelet transform (WT) k2-weighted EXAFS contour plots of the CoN@OCNT and reference samples.
