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 1. (a) SEM image of TEMPOL@HKUST-1 and corresponding EDS mapping of O, Cu and N. The scale bar is 2 μm. (b) Raman spectra of HKUST-1 and TEMPOL@HKUST-1 in the range of 400–1200 cm 1. The inset in (b) is a magnified image. (c) XRD patterns of HKUST-1 and TEMPOL@HKUST-1. (d) Temperature-dependent XRD patterns of HKUST-1 and TEMPOL@HKUST-1. (e) Fourier-transformed EXAFS spectra of HKUST-1 and TEMPOL@HKUST-1. (f) Normalized Cu K-edge XANES spectra of HKUST-1, TEMPOL@HKUST-1, Cu foil, CuO and Cu2O.
